Material Characterization for Metals / Polymers and Foams

Overview

This introductory class is designed for attendees who would like to gain deep insight into the process of material characterization in LS-DYNA. The class provides a brief overview of all available materials models available in LS-DYNA, followed by familiarizing attendees with several tests to capture key mechanical properties.

Learning Outcome

  • Learn about testing Procedures for Uni-Axial, and proportional loading
  • Review of Metal Plasticity
  • Review of onset of Necking and Instability
  • Review of Elastomers and its properties
  • Review of Recoverable and Structural Foams
  • Know more of the best practices of Material Characterization

Prerequisites

  • Introduction to LS-DYNA

Target Audience: This class is targeted for students and structural engineers involved in large deformation problems and interested to get a deep understanding of the process of material testing and characterization for use in large deformation problems.

Teaching Method: Lectures and Illustrations with Examples

Learning Options: Training materials for this course are available with an Ansys Learning Hub Subscription. If there is no active public schedule available, private training can be arranged. Please contact us.
