Advanced Structural Material Nonlinearities (Traditional GUI)

Prerequisites

B.S. in engineering or engineering experience, Introduction to ANSYS (Traditional GUI) as well as the Basic Structural Nonlinearities Course. Knowledge of finite element theory highly recommended.

Description

This ANSYS training course will focus on element selection and the wide range of constitutive models available in ANSYS and is intended for intermediate and advanced ANSYS users. This 2-day specialized ANSYS training course will focus on rate-independent plasticity, rate-dependent nonlinear material behavior (creep and viscoplasticity) and hyperelasticity. Attendees at this ANSYS training course will learn the appropriate element formulations to use, the input of nonlinear material parameters, and the applicability of the various constitutive models for engineering use.
