Ansys nCode DesignLife
Two-Day CourseThe objective of this course is for attendees to develop a strong expertise in the use of Ansys nCode DesignLife for durability and fatigue analysis. The course also demonstrates several examples of setting up and solving DesignLife simulation within the native Mechanical GUI using the “Mechanical Embedded DesignLife” ACT extension. The course covers a broad array of topics focusing on stress life for high cycle fatigue to strain life for low cycle fatigue studies, duty cycle vibration fatigue to simulate virtual shaker table test, as well as seam weld fatigue on thin plate weldments meshed with shell finite elements to solid welds on thicker tubular structures.
The 2-day course includes training materials from Ansys, Inc. that delivers nine instructor-led lectures and ten workshops, as well as DRD Supplementary workshops that demonstrates additionally eight practical examples of fatigue covering different applications.
Prerequisites for this course are DRD’s Introduction to Ansys Mechanical course, and/or some level of proficiency with the Ansys Mechanical user interface.

Workshop 1: Fatigue Analysis of a Simple Shaft under Combined Bending and Torsion Loads
The goal of this workshop is to calculate the fatigue life of the drive shaft using Ansys nCode DesignLife time series loading. The stresses from unit bending and torsion load cases in Mechanical are paired with corresponding measured load histories to generate stress history that allows DesignLife to perform fatigue calculations using Rainflow Cycle Counting and damage assessment using Miner’s Rule.
