Workshop 2.1 – Rotary Draw Bending

This workshop involves bending a “Profile” by 70 degrees using a rigid tool. In this example, the rigid “Rotating Die” and “Clamp Die” will rotate about the Y axis dragging the “Profile” along as it slides along the stationary Mandrel. The “Pressure Die” translates axially along the Z axis while it maintains pressure against the “Profile” as it’s formed over the circular trajectory of the “Rotating Die”.

Workshop 2.2 – Drop Test Wizard

This workshop demonstrates the use of the Drop Test Wizard built into Ansys Mechanical to set up and simulate dropping a circuit board from a height of 1 meter.

Workshop 3.1 – Postprocessing with LS-PrePost

This workshop navigates into the LS-PrePost environment to review some of the postprocessing capabilities with LS-PrePost interface, which is included with Ansys LS-DYNA.

Workshop 4.1 – Impact on Tubes  

In this workshop two nested (concentric tubes) are struck by an impactor approaching at an initial velocity of 30 meters per second. The tubes are connected at outer ends through caps and supported by rotatable cylinder.

Workshop 5.1 – Quasi-static

This workshop utilizes the tube impact test example that involves dropping a tool to hit the tubes. In this workshop; however, we conduct a Quasi-static analysis to study the load from a hydraulic cylinder. The speed of the cylinder is based on the hydraulic pump and the controls system and can take a few seconds to run. It would take a long time to run this in the physical time frame, but the concept of Quasi-static simulation can help accelerate it.

Workshop 7.1 – Meshing

This workshop gives users experience with generating a uniform mesh for both solids and shells with a specific number of element divisions on curved geometry.

Workshop 8.1 – Drop Test

In this workshop we perform a drop test simulation in which we drop a mobile phone from a height of 1.5 meters.

Workshop 8.2 – Bird Strike

In this workshop an impact simulation is performed in order to study the effect of a bird strike on an aircraft wing section. The bird is modeled using Smooth Particle Hydrodynamics (SPH).

This workshop gives the user some experience with using multiple rosettes, multiple oriented selection sets, and tapering of core materials to define complex composite layups.

In this workshop users will learn how to use selection rules to modify the composite layup of a class 40 boat in order to increase its reserve against failure.

This workshop continues Workshop 1 – Basic Sandwich Panel. The layup is modified and reinforced in order to increase the panel’s strength, and the mesh is refined in order to obtain more accurate results. Selection rules and tapers are employed in order to create a desired layup. 

In this workshop, users will generate and evaluate a composite model of a doubly-curved tensile test specimen. This model will use solid elements instead of shell elements in order to accurately capture stress distributions in thick geometry where plane stress assumptions do not apply.

This workshop demonstrates the use of cut-off rules for ply tapering. It also goes through the procedure of applying a resin material to wedge elements that represent the tapered section where a ply starts or ends in a solid composite model.

This workshop will take users through the complete process of modeling, solving, and post-processing a composite model. Solid geometry will be used to generate a variable core thickness in a complex pattern.

The boat model from Workshop 3 will be used to practice with a variety of post-processing tools, including sampling points to obtain through-thickness results.

This workshop will use Workbench parameters to modify the laminate of a composite part. Multiple designs will be evaluated in order to identify which design has the best performance in terms of several composite failure modes.

This workshop is nearly identical to the previous workshop with the difference being that the fast solution method is used instead of the full method. This method assumes a uniform temperature distribution and applies to relatively thin (less than 5 mm) composite structures.

In this workshop users will build on what they learned in the previous workshops to not only predict the composite curing process induced distortions but also compensate for them in the tooling geometry to produce a composite structure that meets the original design specifications. Attendees will also learn how to simulate post-cure trimming operations.

In this workshop we introduce radiation heat transfer. We compare the results from using radiation boundary conditions in FEA with hand calculations for a case of two parallel plates of known temperature.

In this workshop we continue Workshop 1 by adding radiation to the model, which allows heat to be transferred to and from an internal cylinder containing hazardous materials.

In this workshop we continue the analysis on the hazardous material cabinet, this time performing a transient thermal analysis in order to observe the temperatures of the materials after the exterior is exposed to fire.

In this workshop we model solar radiation using an MAPDL Commands object. We also defeature components that are not important to a thermal analysis, then map the results from the defeatured thermal model onto a full-featured structural model in order to perform a thermal stress analysis.

In this workshop we demonstrate two uses of contact resistance: accounting for imperfect contact and modeling thin bodies with a specified resistance in the thickness direction.

In this workshop we examine how a radiation shield surrounding a high-temperature exhaust pipe affects a nearby windshield.

In this workshop we use Thermal Fluid elements to model fluid flow through a nozzle. The thermal analysis accounts for convection heat transfer between the fluid and the nozzle, as well as a specified mass flow rate of the fluid.

This workshop is designed to provide students with practice modeling assemblies. We read the assembly into Mechanical and perform static stress analysis using default bonded contact to hold the parts together. We then use model branching to make a new version of the model, which has no separation contact instead of bonded contact for some of the connections, and we compare the behavior of the models with bonded and no separation contact in the connections.

Workshop 6: Computing Crack Growth with ANSYS SIFs and the Paris Law on a 2D Pressure Vessel

The objective of this workshop is to provide the groundwork for crack growth analysis. In this workshop, students solve a 2D pressure vessel study for varying crack lengths using Ansys Mechanical with a parametric model.

The workshop then provides a basis for computing crack growth information using a spreadsheet, allows the student to experiment with the crack growth computation, and asks several engineering questions:

·         What crack length causes immediate fracture?
·         Is limit load exceeded?
·         Is the curve fit for crack growth adequate for small cracks?

Workshop 7: SMART Crack Growth on Intersecting Pipes

This workshop is the first of two workshops that demonstrate the use of SMART. Students will learn how to setup an automated crack growth analysis using the Semi-Elliptical Crack combined with SMART Crack Growth object. Detailed definition of the Paris Law material constants for crack growth is also covered.

Automated crack growth has a host of new results post-processing options for Crack Extension, Equivalent Stress Intensity Range and Cycles; students will work through these options as well.

Workshop 8: SMART Crack Growth on a Casting with a Thermal Gradient

In this workshop, students learn how to create a crack using a 3D surface representation of the crack surface. This is made possible via the Arbitrary Crack feature, which allows a complex, non-planar 3D surface to be used as a basis for generating a crack mesh.

Workshop 9: SMART Crack Growth on a Casting with an Initial Stress State

This workshop is a continuation of workshop 8, where students load a casting with a thermal gradient and grow a crack. In this workshop, an initial stress state is set up that includes this thermal gradient and bolt pretension. The initial stress state is passed to a downstream analysis where the cyclic load to grow the crack is pressure. SMART crack growth is used here; Ansys automatically handles this initial stress state each time the crack calculation is performed.

Workshop 10: Adhesive Failure Modeling with Contact Debonding

This workshop demonstrates modeling failure of an adhesive layer via bonded contact. Students define a cohesive zone material model with properties for maximum normal stress and critical fracture energy. The benefit of this capability is that the adhesive layer does not need to be directly modeled. This is a huge benefit as the adhesive layer is typically much smaller in thickness compared to the parent parts bonded together. A secondary benefit is the mesh does not need to be the same on either side of the interface, as contact is used to initial tie the parent parts together.

Workshop 11: Adhesive Failure Modeling with Interface Delamination

This workshop demonstrates a second method to simulate interface failure; interface delamination. A similar material model is defined for this method. However, contact is not required for this capability. Instead, the mesh on both parent parts must be the same at the interface with the adhesive. This is accomplished through clever meshing or match mesh controls. The interface delamination capability also has another special use case: delamination modeling with composite models created in Ansys Composite PrepPost.
