Non-Linear Structural Dynamics, Shock, Fluid-Structure Interaction

• Large-scale deformation, fracture and post-fracture behaviour
• Plasticity and stabilisation as a function of the strain rate
• Inhomogeneity and anisotropy of stiffness (fibre composite material)
• Rubber-elastic behaviour (elastomers)
• Fluid-structure interaction in the case of detonations
• Propagation of stress waves

Our service portfolio

• Safety analyses with regard to deformation, failure and shock
• Crash safety for vehicles and transport containers (e.g. CASTOR casks)
• Simulation of the opening behaviour of convertible tops
• Simulation of penetration processes, e.g. turbine blade impacting turbine housing
• Pyroshock loading of aerospace structures
• Pre- and post-shot analyses of underwater explosions including computer support for tests
• Analysis of stability and vulnerability of ships, submarines and other underwater vehicles
