Begleitende Seminare

In der Woche vor und nach der Konferenz finden in Ulm, Stuttgart und ggf. online konferenzbegleitende Seminare statt.

Introduction to SPG Method for Manufacturing and Material Failure Analysis

Termin: 4. Oktober 2021
Gebühr: 600,- Euro*
Ort: Ulm
Referenten: Youcai Wu (LST LLC)
Kurssprache: Englisch
Anmeldung

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.

Electromagnetism in LS-DYNA

Termin: 4. Oktober 2021
Gebühr: 600,- Euro*
Ort: Ulm
Referenten: Iñaki Çaldichoury (LST LLC)
Kurssprache: Englisch
Anmeldung

This course provides an introduction to the Electromagnetics (EM) solver in LS-DYNA. The Maxwell equations are solved in the Eddy-Current approximation suitable for cases, where the propagation of electromagnetic waves in air (or vacuum) can be considered as instantaneous. The solver is coupled with the solid mechanics and thermal solvers of LS-DYNA allowing the simulation and solution of applications such as magnetic metal forming, welding, bending, induced heating, resistive heating and so forth.

The course includes a presentation of the solver’s general principles and applications, a complete keyword description for setting up an Eddy-Current problem, an introduction to the more advanced features (Inductive heating problems, exterior magnetic field, magnetic materials and so forth) as well as an advanced description of the available controlling tools to ensure a safe analysis.

Key electromagnetic concepts are reviewed throughout the course and a general knowledge about electromagnetics is therefore appreciated but not mandatory.

Explosives Modeling for Engineers

Termin: 4. Oktober 2021
Gebühr: 600,- Euro*
Ort: Ulm
Referenten: Paul Du Bois, Len Schwer (Consultants)
Kurssprache: Englisch
Anmeldung

This class focuses on the application of LS-DYNA to modeling explosives. LS-DYNA simulations involving explosives can be modeled on several engineering levels from simple application of equivalent pressure histories via *LOAD_BLAST_EN-HANCED, explicit inclusion of explosive charges using Equations-of-State and detonation via *IN-ITIAL_DETONATION, and detonation of explosive due to impact using
*EOS_IGNITION_AND_GROW-TH_OF_REACTION_IN_HE. The analyst selects the appropriate degree of model sophistication to satisfy the intended use of the model results.

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.

This training class is intended for the LS-DYNA analyst possessing a comfortable command of the LS-DYNA keywords and options associated with typical Lagrange and Multi-Material Arbitrary Lagrange Eulerian (MM-ALE) analyses. The training class will attempt to provide the analyst with the additional tools and knowledge required to model explosives for a range of applications. The theory and illustrations portions of the class will benefit LS-DYNA users and non-LS-DYNA users alike.

Elementtypen & nichtlineare Aspekte

Termin: 7. Oktober 2021
Gebühr: 525,- Euro*
Ort: Ulm
Referenten: André Haufe (DYNAmore)
Anmeldung

Dieses Seminar behandelt verschiedene nichtlineare Aspekte im Zusammenhang mit LS-DYNA. Zentrales Thema ist hierbei die Diskussion der diversen Elementformulierungen, die in LS-DYNA verfügbar sind. Auf theoretische Gesichtspunkte und anwendungsorientierte Überlegungen wird gleichermaßen eingegangen. Die zur Verfügung stehenden nichtlinearen und linearen Gleichungslöser werden erörtert und die Möglichkeiten der impliziten Analyse aufgezeigt. Außerdem werden ortsadaptive Verfahren für nichtlineare Probleme vorgestellt.

Das Seminar richtet sich an Anwender, die Grundkenntnisse in der Theorie der Finiten Elemente sowie in der Handhabung von LS-DYNA haben und daran interessiert sind, ihre theoretischen Kenntnisse zu vertiefen.

NVH, Frequency Domain, Fatigue

Termin: 7. Oktober 2021
Gebühr: 600,- Euro*
Ort: Ulm
Referenten: Yun Huan (LST LLC)
Kurssprache: Englisch
Anmeldung

The objective of the training course is to introduce the frequency domain vibration, fatigue 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, fatigue 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.

Resistive Heating and Battery Modeling

Termin: 7. Oktober 2021
Gebühr: 600,- Euro*
Ort: Ulm
Referenten: Iñaki Çaldichoury (LST LLC)
Kurssprache: Englisch
Anmeldung

This course is based on the Electromagnetics (EM) solver of LS-DYNA. The EM module computes the Maxwell equations and is embedded into LS-DYNA following LSTCs one-code strategy, thereby allowing for an efficiently
coupling to the solid-mechanics and the thermal solver.

The seminar presents the solver’s general principles, a complete keyword description for setting up simulation models, on the one hand, to compute inductive and resistive heating problems. On the other hand, the
modelling of batteries is addressed. Thereby exploiting the Randles-circuit approach to describe the charging and discharging process as well as the accompanying heat production.
