Introduction to Welding Simulation

Date: 18 October
Course fee: 525,- Euro*
Location: Bamberg
Lecturers: Dr. Thomas Klöppel (DYNAmore)
Anmeldung

Due to recent developments in LS-DYNA, the complete welding process can be captured. In this regard, the numerical simulation can be performed in several stages where, for instance, the cooling process as well as the associated warping of the structural components can be computed after each welding stage. Moreover, the choice of a suitable material law also allows considering microstructural transformations in the welding zone itself or in the heat-affected zone. The aim of this seminar is to give the participants a brief introduction to the thermomechanical coupled simulation with LS-DYNA. Herein, the required forms of heat sources and transfer for a successful welding simulation will be discussed and their definition in LS-DYNA is shown.

NVH and Frequency Domain Analysis with LS-DYNA

Date: 18 October
Course fee: 550,- Euro*
Location: Bamberg
Lecturer: Dr. Yun Huang (LSTC)
Anmeldung

In this seminar, an overview is given on the acoustic and frequency do main vibration features of LS-DYNA. It will particularly focus on the application of these features in vehicle NVH simulation. The seminar addresses 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. All required knowledge to run these simulation problems with LS-DYNA will be presented in detail.

Advanced Damage Modeling: Orthotropic Materials

Date: 18 October
Course fee: 525,- Euro*
Location: Bamberg
Lecturers: Dr. Filipe Andrade (DYNAmore)
Anmeldung

This one-day course is intended for engineers and researchers who already have relevant experience in the area of material damage and failure. The main goal of this class is therefore to present the current modeling capabilities of LS-DYNA regarding the simulation of complex degradation phenomena typically observed in materials that are used in industrial applications. In this class some important concepts regarding orthotropic and anisotropic damage are reviewed as well as typical modeling approaches found in the literature. Advanced damage models implemented in LS-DYNA are then presented in detail. In particular, attention is devoted to the modular damage/failure model in *MAT_ADD_GENERALIZED_DAMAGE for which some simple application examples are shown.

Introduction to SPG Method for Manufacturing and Material Failure Analyis

Date: 18 October     
Course fee: 550,- Euro*
Location: Bamberg
Lecturer: Youcai Wu (LSTC)
CANCELLED


This one-day class will introduce the smoothed particle Galerkin (SPG) method and its application in manufacturing and material failure analysis. The SPG method is developed for modeling large deformation and material failure in semi-brittle and ductile materials in three-dimensional solid structures, in which a bond-based failure mechanism is utilized to model material failure. This method can be used to bridge the Lagrangian FEM and is exclusively available in LS-DYNA.

The class will provide the fundamental background, LS-DYNA keywords, practical applications (in analyzing relatively low speed manufacturing processes such as metal cutting, FDS, SPR and high velocity impact penetration on concrete and metal targets) with some experimental validations and latest developments.

 

Methods for Simulating Short Duration Events

Date: 18 - 19 October
Course fee: 1.200,- Euro*
Location: Bamberg
Lecturers: Paul Du Bois (Consultant); Dr. Len Schwer (Schwer Consulting)
Anmeldung

This two day class provides instruction on the selection and use of the LS-DYNA solvers used for analyzing blast and penetration related problems. It addresses experienced LS-DYNA analysts of typical Lagrange analyses. The training class will provide understanding required to make appropriate LS-DYNA modeling decisions and convey the level of confidence in predictive simulation results. Insights into modeling and simulation are illustrated through simple examples and numerous modeling ‘tricks’ and options are discussed. An emphasis is placed on modeling techniques, guidelines for which technique(s) to select, which techniques work well and when, and possible pitfalls in modeling choice selections.

Blast Modeling with LS-DYNA

Date: 22 - 23 October
Course fee: 1.200,- Euro*
Location: Stuttgart
Lecturers: Paul Du Bois (Consultant); Dr. Len Schwer (Schwer Consulting)
Anmeldung

LS-DYNA is unique in offering analysts the choice of Lagrange, Eulerian (ALE) and Simple Engineering solvers, and a combination of these solvers. One example is simulating high energy events such as blast loading. In addition to air blast, the traditional focus of blast modeling has recently become important. This class focuses on the application of LS-DYNA for the simulation of high energy events. Methods of analysis and modeling with LS-DYNA are illustrated through simple case studies. However, this training class is not a substitute for the in-depth treatments presented in the associated LS-DYNA training class, i.e. “ALE/Eulerian and Fluid Structure Interaction”.

LS-OPT – Introduction and Optimization

Date: 22 - 24 October
Course fee: 1.575,- Euro*
Location: Stuttgart
Lecturer:  Katharina Witowski (DYNAmore)
Anmeldung

LS-OPT is an independent, comprehensive optimization program from LSTC. It is ideal for solving strongly non-linear optimization problems and is highly suitable for use in combination with LS-DYNA or any other solver. LS-OPT functions on the basis of a special, highly effective response surface method. The program also includes stochastic methods for assessing the robustness of FE models and illustrating dependencies between optimization variables and desired values. Input from the user is supported by a comfortable graphical user interface. The seminar gives an introduction to the program LS-OPT. General theoretical aspects of the Response Surface Method are discussed and the possibilities of applying this method in LS-OPT are especially explained.

Penetration Modeling with LS-DYNA

Date: 24 - 25 October
Course fee: 1.200,- Euro*
Location: Stuttgart
Lecturers: Paul Du Bois (Consultant); Dr. Len Schwer (Schwer Consulting)
Anmeldung

In addition to high energy events, penetration events are typically associated with large deformations, damage, and failure both on the material and structural level. During the past decade successful modeling of such damage and failure has moved steadily from a “Black Art” to a widely accepted engineering practice. This class focuses on the application of LS-DYNA and provides analysis methods and modeling techniques, which are illustrated through simple case studies. However, this training class is not a substitute for the in-depth treatments presented in the associated LS-DYNA training classes, i.e. “ALE/Eulerian and Fluid Structure Interaction” and “Smoothed Particle Hydrodynamics (SPH) in LS-DYNA”, respectively.

 

Explosives Modeling for Engineers

Date: 26 October
Course fee: 600,- Euro*
Location: Stuttgart
Lecturers: Paul Du Bois (Consultant); Dr. Len Schwer (Schwer Consulting)
Anmeldung

LS-DYNA simulations involving explosives can be modeled on several engineering levels from simple application of equivalent pressure histories via *LOAD_BLAST_ENHANCED, explicit inclusion of explosive charges using Equations-of-State and detonation via *INITIAL_DETONATION, detonation of explosive due to impact using *EOS_IGNITION_AND_GROWTH_OF_REACTION_IN_HE. This training class is intended for the experienced LS-DYNA analyst associated with typical Lagrange and Multi-Material Arbitrary Lagrange Eulerian (MM-ALE) analysis. The training class will provide the analyst with the understanding required to model explosives for a range of applications in LS-DYNA.
