Ansys Explicit Dynamics

Course Overview

This course will enable you to develop the basic skills necessary to implement complete Explicit Dynamics solution procedures in Ansys Mechanical. Explicit Dynamics is the preferred choice when simulating the dynamic response of highly transient, highly nonlinear physical phenomena like drop testing and high-speed impact. You’ll utilize the extensive library of nonlinear material models and body-to-body contact to produce faithful representations of real-world physical systems.

Prerequisites

  • Completion of the Ansys Mechanical Getting Started course is required.
  • A technical education and a background in the fundamentals of finite element analysis are recommended. 
  • A basic background in the following areas is also recommended: dynamics, mechanics of materials, material modeling, and the physics of transient dynamic events. 
  • An engineering degree is not required.

Teaching Method

Lectures and computer workshops to give students the knowledge and confidence they’ll need to apply what they’ve learned to their own designs.

Learning Outcome

Following completion of this course, the student will be able to:

  • Understand how the explicit solution method differs from other methods used to perform dynamic analysis in Ansys and to choose when it is most appropriate.
  • Apply the proper workflow when setting up an explicit analysis and take advantage of the Drop Test Wizard to automate the workflow.
  • Build efficient meshes that take full advantage of the computational speed afforded by the explicit solution method.
  • Access an extensive library of material models suitable for predicting failure and post-failure behavior of your designs.
  • Model and simulate a wide variety of true-to-life interactions among component parts within a larger system-level model.
  • Apply the proper solution settings to your explicit analyses to ensure speed and accuracy.
