Begleitende Seminare

1. - 2. Oktober, Stuttgart

The objective of the training course is to introduce the frequency domain vibration and acoustic features of LS-DYNA to users, and give a detailed look at the application of these features in vehicle NVH simulation.  This course is recommended for engineers who want to run NVH or other frequency domain vibration and acoustic simulation problems with LS-DYNA. This course is useful for engineers and researchers who are working in the area of vehicle NVH, aircraft/spacecraft vibro-acoustics, engine noise simulation, machine vibration testing and simulation, etc.

Meshfree EFG, SPG and Advanced FEM in LS-DYNA

9. -10. October, Stuttgart, Germany

Attendees of this seminar will be introduced to the application of the meshless method “Element-Free Galerkin” (EFG) in LS-DYNA. The seminar will outline the theoretical foundations and thoroughly refer to the settings required in the LS-DYNA input deck to carry out a successful nonlinear EFG simulation. Herein, the difference between the conventional EFG formulation and the adaptive or discontinuous formulations will be explained. Common applications of the conventional EFG formulation are materials made of rubber or foam that undergo large deformations. The adaptive EFG formulation is the method of choice for the efficient simulation of cutting, bulk forming and forging processes. In particular, the new features of local mesh refinement in combination with the implicit time integration are the key enablers for these processes. Moreover, fracture simulations can be carried using the discontinuous EFG formulation. With the aid of many workshop examples, the attendees will receive a good understanding of how to use the different EFG formulations. The instructor Dr. Cheng-Tang Wu is a senior software developer at LSTC and was significantly involved in the development and implementation of the meshless method EFG in LS-DYNA. This seminar is recommended for engineers who have already worked with LS-DYNA and would like to use a meshless method.

ALE und Fluid-Structure Interaction

9. - 10. Oktober, Stuttgart

In this seminar, you receive comprehensive information directly from one of the program developers about the latest developments of the features provided by the solver LS-DYNA to analyse fluids and, in particular, the fluid-structure interaction using its Arbitrary Lagrangean Eulerian (ALE) capabilities. The theoretical background to fluid modeling in LS-DYNA is presented and illustrated with several practical applications. Problems solved during the workshop include tank sloshing, tank dropping (partially and completely filled), viscous flow in a channel, underwater explosion, bird strike, ship collision and acoustics in air and water. The seminar is directed towards advanced LS-DYNA users, whereas prior knowledge of fluid dynamics is not required.

Concrete and Geomaterial Modeling

9. - 10. Oktober, Stuttgart

The course starts from the common ground of introductory metal plasticity constitutive modeling and successively builds on this base adding the constitutive modeling features necessary to model concrete and geomaterials. The LS-DYNA constitutive models covered are adequate for modeling most types of rock, all concretes, and a large class of soils. The course is intended for those new to concrete & geomaterial constitutive modeling, but will also be
useful to those seeking a more in-depth explanation of the LS-DYNA concrete and geomaterial constitutive models covered.

Blast Modeling

13. - 14. Oktober, Stuttgart

This class focuses on the application of LS-DYNA for the simulation of high energy events. The analysis methods, and modeling, are illustrated through case studies. An emphasis is placed on modeling techniques: guidelines for which technique(s) to select, insights into which techniques work well and when, and possible pitfalls in modeling choice selections.

Vortragende: Paul Du Bois (Consultant) und Len Schwer (Schwer Engineering & Consulting)

Penetration

The modeling methods are illustrated through case studies with sufficient mathematical theory to provide the user with adequate knowledge to then confidently apply the appropriate modeling method.
