Introduction to Ansys LS-DYNA

Course Description

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.

After completion of this course users 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.

Prerequisites:

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

Audience:

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