Ansys Workbench
LS-DYNA (Self-paced Learning Available)

Course Overview

This course covers the use of Ansys LS-DYNA inside Workbench Mechanical. Ansys LS-DYNA is useful for the analysis of problems involving contact, large deformation, nonlinear materials, transient response, and/or problems requiring explicit solutions. Common applications for which LS-DYNA excels include safety and stability, crash test and drop test simulation, as well as forming applications.

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.

Target Audience

Mechanical Engineers, Impact Dynamics Engineers, Drop Test Engineers and Designers working with structures that experience short-duration and/or high-speed impact events.

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, you will be able to:

  • Understand how the explicit solution method differs from other methods used to performed dynamic analysis in Ansys and to choose when it is most appropriate.
  • Choose the proper solution parameters unique to Ansys LS-DYNA that will ensure an accurate and efficient solution.
  • Take advantage of common modeling abstraction techniques (rigid bodies, point and distributed masses) to produce efficient and realistic simulations.
  • Understand and apply various Contact conditions unique to Ansys LS-DYNA according to best practice guidelines.
  • Leverage the robust nonlinear analysis capabilities afforded by LS-DYNA in the solution of quasi-static problems.
  • Assign mesh controls required to produce accurate and efficient explicit solutions.
  • Choose from several LS-DYNA element formulations while understanding the trade-offs between accuracy and efficiency.
  • Access advanced functionality of LS-DYNA using keyword snippets.
