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 ...

Global sensitivity analysis provides information about the respective significance/contribution of structural input random parameters (or combinations thereof) onto considered responses. The identification of non-relevant and relevant ...

In the paper an approach for structural health monitoring is introduced comprising uncertain structural analysis, assessment of damage and performance by uncertainty-indicators as well as prognosis of structural behavior and lifetime. ...

This talk introcudes into a new development methodology, using FE dummy modeling as a data source, discusses model updates and development as well as model handling.

The curtain airbag is usually simulated by a uniform pressure method in which the pressure of the airbag is considered as constant. This is correct when the airbag is fully deployed. However, this assumption is not valid during the ...

The use of math-based tools has reduced the need for hardware prototyping and testing, which in turn reduces a vehicle’s development time and cost. LS-DYNA has been extensively utilized in the crashworthiness community to improve ...

This talk gives an overview of material and component tests as well as sled tests, barrier design and abdomen calibration regarding dummy validation.
