HyperCrash is a new preprocessing environment for LS-Dyna that offers a comprehensive toolset for all crash and safety modeling needs. With a modern and intuitive graphic user interface, HyperCrash provides functions for fast model ...

The increased sophistication of impact models and the existence of many kinematic mechanisms in them, along with the need to study many load cases, has forced the analysts to use multi-body solvers to reposition their models. This has ...

For a number of years the application of efficient gradient based design optimisation has been available for Finite Element Analysis (FEA) working within the linear loading domain. Methods such as Topology optimisation have become ...

Today, real-world crashworthiness optimization applications are limited to sizing and shape optimization. Topology optimization in crashworthiness design has been withstanding until today any attempt of finding efficient solution ...

Over the last years, total vehicle weights have risen significantly. With their direct influence on the power demand of vehicles, the reduction of weight is one among other measures in order to decrease the fuel consumption and CO2 ...

As the optimization techniques are used more extensively during the product development life cycle, the use of a tool that organizes the definition of an optimization process becomes essential. The set up of combined shape and ...

This paper describes a multi objective optimization of a crash management system using LS-OPT. Shape optimization is done using ANSA’ s Morphing Tool as pre-processor in LS-OPT. Several objectives from two different load cases are ...

This paper provides an overview of current LS-OPT® development and focuses mainly on the following new features: (i) New wizards for LS-Dyna statistics and metamodel-based optimization, (ii) visualization of the Pareto Optimal Front ...

In this presentation new possibilities for the material characterization of foams are shown. Especially the presentation focuses on the testing system 4a Impetus and its interaction with LS-OPT. To determine meta-models, that describe ...
