# Introduction LS-DYNA/LS-PrePost for explicit and implicit analysis

This is a suite of tutorials with the aim to get new users up and running with using primarily LS-DYNA and LS-PrePost for explicit and implicit analysis. A tutorial for LS-OPT is also included If you teach at a university and would like to use the tutorials in your classes, you are welcome to do so.

## Contents

### 0. Introduction

• Presents information about LS-DYNA and LS-PrePost. Important to read before starting with the other tutorials.

### 1. Getting started

• Learn how to set up a simple finite element model in LS-PrePost.

### 2. Tensile test

• Perform a tensile test, both explicit and implicit, and get familiar with basic material modeling.

### 3. Crashbox impact analysis

• Understand how to use contacts in LS-DYNA by compressing a box. Using mesh tools in LS-PrePost and how the explicit time step is calculated are also covered in this tutorial.

### 4. Eigenvalue

• Perform an eigenvalue analysis of a tire.

### 5. Hardening and failure

• Get familiar with how to use material models for isotropic and kinematic hardening. Failure criteria are also introduced in this exercise.

.

### 6. Bolt pre-stressing

• This tutorial is divided into two parts. The first part consists of using the geometry and mesh tools in LS-PrePost. The second part includes how to prestress a bolt using dynamic relaxation.

.

### 7. Parameter identification using LS-OPT

• An introduction to the optimization program LS-OPT. A parameter identification will be performed.

### 8. 2D CFD-analysis with vortex shedding

• Get to know the Incompressible Computational Fluid Dynamics (ICFD) solver in LS-DYNA using this classical 2D-vortex shedding simulation.

.

### 9. Fluid-structure interaction with the ICFD solver

• Set up a basic 3D fluid-structure interaction simulation using the Incompressible Computational Fluid Dynamics (ICFD) solver in LS-DYNA.
