Contact UsExplicit Dynamics in LS-DYNA
Course Overview:
This course teaches experienced Ansys Mechanical users advanced skills in performing impact and drop test analyses.
Learn to distinguish problems that should be solved explicitly versus implicitly, perform all procedures for an explicit dynamic analysis, and identify and choose element types, materials, and commands used in explicit dynamic analyses.
This class is beneficial to engineers who analyze problems involving contact, large deformations, nonlinear materials, high-frequency response phenomena, high-speed metal forming, ballistics, crash impact, or problems requiring explicit solutions.
Prerequisites:
FEA 101 Workbench Mechanical Introductory
Who should take this course:
- Experienced Ansys Mechanical users who are looking to learn advanced methods to perform advanced analyses via Ansys LS-DYNA Training in Explicit Dynamics
With completion of this Ansys FEA Training, you will:
- Be able to perform various explicit dynamics analyses with the Ansys LS-DYNA platform
- Receive an official certificate of completion with professional development hours that can qualify for the continuing education requirements upon renewal of a PE license in most states.
