Ansys Explicit
Dynamics Theory

Course Overview

We are able to comprehend the physics of brief-duration events thanks to Explicit Dynamics. Events that take place in milliseconds or even less time, such as a ball hitting a bat, a phone falling to the ground, or a vehicle crash can be simulated using Explicit Dynamics.

Explicit Dynamics method may also be used to simulate cases with high nonlinearities, where obtaining convergence via implicit methods is not possible. We discuss the theory underlying Explicit Dynamics simulations in this course.

Prerequisites

This course is an introductory course to Explicit Dynamics Theory. While no previous knowledge of Explicit Dynamics is required, fundamental knowledge of the finite element method is required.

Teaching Method

Self-paced videos, with accompanying hands-on tutorials to validate practical knowledge.

Learning Outcome

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

  • Understand the distinctions between Implicit and Explicit methods and when to utilize each one.
  • Adjust model parameters to obtain an optimum time step size for efficient simulations.
  • Detect and remedy undesirable behaviors such as volumetric locking, shear locking and hourglass behavior.
  • Learn how to check the energy balance of the system to ensure solution accuracy.
