Consumer products like cell phones, personal digital assistants, dish washers or cookers, to name just a view of them, are often exposed to drop during transportation to the customer and during usage in life time. Pre-damage, failure ...

Interference fits are a commonly used means to couple shafts and wheels for example. The usual dimensioning is performed by a static verification. As long as the system geometry is not too complicated and the deformation is assumed to ...

Clamping rings are used in a wide range of mechanical applications in order to assemble two or more cylindrical parts, e.g. tubes and pipes, pressure vessels and tanks. Another application area of clamping rings is in turbo engines, ...

The use of computational mechanics methods is now largely adopted in the field of Road Side Safety. They are certainly interesting in the context a product development. However, the application of these methods in the certification ...

This paper describes the development of the Roadside Safety Verification and Validation Program (RSVVP), a software that automatically assesses the similarities and differences between two curves. This program was developed to assist ...

This paper will describe the work carried out to compare the experimental response of the car using a four actuator vibration rig and that obtained from an LS-dyna analysis using the same loading spectrum as that used in the physical ...

The dynamic behaviour of a roots vacuum booster with two rotors is presented. The dynamic response of the structure is, thereby, investigated using an explicit analysis for the crash behaviour and an implicit analysis for the ...

This paper deals with the development of a finite element model of a 40 mm Case Telescoped Ammunition and its associated gun, able to describe the in-bore travel of the projectile during firing. This work is part of a PhD thesis, ...

A research programme is being undertaken at TNO to investigate vulnerability reduction on warships. In this framework, studies have been performed regarding the structural damage due to both an internal missile explosion and close in ...

A coupling method recently implemented in LS-DYNA® allows empirical explosive blast loads to be applied to air domains treated with the multi-material arbitrary Lagrangian-Eulerian (ALE) formulation. Previously, when simulating ...
