Development processes for more complex new products and better performance require necessarily verification through digital simulation. Due to shortened development cycles the time to answer questions about reliable product ...

From concept to engineering and from design to test and manufacturing; engineering relies on powerful virtual development solutions. Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) are used in an effort to secure ...

When concrete impact and penetration simulations are discussed, the question of increased strength due to high strain rates arises. Many concrete material modelers cite and use the seminal work of Bischoff and Perry (1991), or the ...

The local damages of the concrete plate are produced by high velocity impact of rigid projectile. In order to represent the cracking or perforation behaviours of the concrete, SPH is appropriate method because of completely mesh ...

The behaviour of reinforced concrete in quasi static regimes has been investigated extensively but there have been few investigations into its transient behaviour, especially under low velocity regimes. This paper describes the finite ...

Superconducting cables are one of the key technical solutions used for generation of strong magnetic field in modern tokamaks. It is very important for engineers to be able to predict the mechanical deformations of ...

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 ...
