******************* Course Structure ***************************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. Brief outline of the course is as following:1. FEA/CAE basics and types of simulation Product life cycle management Branches of CAE Intuition of CAE Steps in CAE Types of analysis. 2. Introduction to LS-PrePost Deep dive into preprocessing using LS-PrePost. GUI of LS-PrePost. Handling a model using different approaches.3. Keyword Arrangement in LS-Dyna Running a simple simulation File format and keyword structure in LS-Dyna. Keyword Arrangement: Nodes and Elements Keyword Arrangement: Parts, Section, Material LS-Dyna Manuals Example: Cube Under Pressure Keyword Arrangement: Database and Control Keyword Arrangement: Boundary and Constrained4. Material Modelling for LS-Dyna Material Non-Linearity Conversion of Engineering Stress, Strain to True Stress, Strain Material: MAT024 PIECEWISE LINEAR PLASTICITY Example: Tensile Test with Non-Linear Material 5. Important Keyword *Include Example: Include File Structure Introduction to Hourglass Examples on Hourglassing and control TimeStepNew topics and projects are coming soonIf you have any doubt fell free to contact me.So Enroll now and start this exciting journey with me.******************* Course Updates ***************************1.
