Description
Hello learners,
I welcome you all to this comprehensive course on LS-DYNA. Objective of this course is to get started from very basic understanding of FEA and gradually get you well versed with LS-DYNA. LS-DYNA is one of the most best and popular explicit code out there. LS-DYNA is used in almost all the industries that you can imagine. In this course though we will be taking examples of only structural analysis from automotive domain.
Skills you will gain at the end of the course
You will learn different types of analysis and fundamental difference between them.
You will learn to setup a model in LS-PrePost, edit the model in Notepad++ and solving the model using LS-Dyna.
You will learn various aspect of material modelling in LS-Dyna.
You will get overall understanding of important concepts in explicit such as hourglassing, timestep and mass scaling.
