Der Vortrag "Numerische Simulation von Schlagbelastungen an unsymmetrischen CFK-Sandwich Platten" gibt eine Übersicht über die Thematik Schlagbeschädigung von CFK-Sandwich als auch eine Einfürhung in Modelle zur Simulation von ...

Numerical simulations of blast resistant windows and facades will be presented and compared with test results. The focus of the presentation is the prediction of different processes of fracture and damage. The numerical model includes ...

Material models for thermoplastic polymers are still subject of research and development. The commonly used material models for crash simulation were developed for metals. This paper shows a way from material data to component testing ...

A new 8-node adaptive cohesive element is developed and implemented in LS-DYNA to stabilize the finite element simulations of delamination propagation in composite laminates under transverse loads. In this model, a pre-softening zone ...

Cellular structures are often used as crash absorbers due to their high capability of impact energy absorption. During the impact the intercellular walls buckle and cells collapse which results in impact energy absorption through ...

Energy absorbing foam padding is widely applied in various areas of modern cars in conjunction with increasing number of airbags as passive safety systems. High efficient energy absorbing foams which can be used to optimise energy ...

Im vorliegenden Beitrag erfolgt die Diskussion eines mikromechanischen Materialansatzes zur numerischen Simulation der Steifigkeitsreduktion von Werkstoffen. Die Ursache dieser Materialdegradation besteht in der Evolution von Poren ...

With increasing requirements on the crash safety of automotive components and on virtual prototyping it becomes more and more important to model damage behaviour of structural components in crash simulations. Especially high strength ...

The quest for predicting the material failure of ultra high strength steel introduces various approaches in simulations. BTR165 is ultra high strength steel used for safety beams in the vehicles. For the analyses of failure model, ...

The crash behaviour of automobile components from an aluminium die cast alloy and from an extruded profile was characterised under different load conditions and simulated with two damage models (Gurson, Johnson-Cook). The influences ...
