Welding Simulation

T. Loose (DynaWeld)

In this workshop, two simulation models will be presented addressing the Gas Metal Arc Welding of a T-joint as well as a Laser Welding overlapp joint with a tension test.

Simulation of Fluid-Structure Interaction between Injection Medium and Balloon Catheter using ICFD

L. Wiesent, Prof. M. Wagner (OTH Regensburg)

MPIP - Material Parameter Identification Process with 4a impetus

A. Fertschej, B. Jilka (4a engineering)

The material card generation using 4a impetus solution is shown exemplary for thermoplastic materials. The latest software features of 4a impetus are presented, especially the “Autofit” workflow and implementation of anisotropic material laws are main topics. New test methods focusing on failure estimation and component validation complete the workshop topic

Besides the presentation there will be time for interactions between the presenters and the audience

Numerical Prediction of the Dynamic Response of Prestressed and Reinforced Concrete Hollow Core Slabs Under Blast Loading

SDM and CAE-Processes with SCALE Solutions

R. Bitsche, G. Geißler (SCALE)

The workshop gives an overview of the SCALE SDM products such as LoCo, CAViT and Status.E.

There will be a discussion on how to benefit from SCALE solutions as a user or project manager. The application of selected uses cases will be presented within live demos. Examples of typical CAE workflows and process automation using SCALE SDM applications are introduced.

A lively discussion at the end of the workshop is very welcome to investigate a potential integration of SDM software in your environment

New LS-PrePost Interface for ICFD Preprocessing

I. Çaldichoury (LSTC)

A new interface for model setup is under development in LS-PrePost where the user can easily assign physical properties and options for his model. LS-PrePost will then automatically translate the definitions into keyword forma

The current capabilities focus on the ICFD solver but will be extended in the future

Explicit and Implicit FE Simulations of Material Tests for Subsequent Durability Analyses

Introduction into the New Optimisation Tools for Forming Simulation with eta/DYNAFORM

M. Merten (DYNAmore)

Recently, DynaForm version 5.9.3 was published, which contains several new features. Particular highlights are the new automatic springback compensation process or the reworked blank & trim line development, which improve the workflow of a toolmaker in daily life

The goal of this workshop is to present these new features and how they work. How they can be an applied will be shown with the aid of a live demonstration on a simple geometry. Attention is drawn on a quick and proper setup for these processes.

Mapping with Envyo

C. Liebold (DYNAmore)

Envyo is a multi-purpose mapping tool which was introduced to the public in 2016 during the German LS-DYNA Forum

The goal of this workshop, is to present the already implemented mapping capabilities and to demonstrate their usage. The general need to map simulation results is shown with the aid of dedicated examples.

The workshop is closed with an open discussion where you can place your own ideas for future mapping developments

LS-OPT Robustness Analysis

K. Witowski (DYNAmore)

The goal of this workshop is to provide an overview of the methods for robustness analysis that are available in LS-OPT. Herein, the basic ideas of direct and metamodel-based Monte Carlo Analysis as well as RBDO/RDO will be discussed.

A life demonstration of how to set up a robustness analysis using thegraphical user interface of LS-OPT and how to visualize and evaluate the results will also be given

Blast Analysis with LS-DYNA

D. Hilding (DYNAmore Nordic)

An overview is given of the available methods in LS-DYNA to calculate explosive blast loads from conventional explosives on structures for structural engineering purposes. Advantages and disadvantages with the different methods will be pointed out. The focus is on air-blast.

The intended audience is LS-DYNA users interested in methods for blast & explosion simulation with the goal to be able to do strength/performance analysis of blast loaded structures. Time permitting, a short demonstration will be given
