Metal-Plastic-Metal (MPM) sheets consists of two metal sheets bonded together by a thin polymer layer. Modelling this sheet structure with a single shell element gives a too stiff response. The large shear deformation in the polymer ...

Active hydro mechanical forming (AHMF) has been developed in order to meet the demand of the automotive industry for economical production of sheet metal parts with more individuality in small lot sizes. Conventional deep drawing of ...

Wear prediction necessitates the investigation of elastic stresses developed in the workpiece material due to impact and sliding of abrasive particles in tribological contact situations. LS-Dyna implicit finite element analysis is used ...

The conventional progressive stamping process used in producing connector pin makes the pin-shift from side to side due to elastic recovery reffered to springback phenomenon. As the solution of this problem, the reverse stamping ...

Foam materials are widely used in automotive industry such as energy absorbers and comfort enhancers. Because of high energy absorbing capability of foams, they became very important in vehicle crashworthiness. So in this manner, FE ...

Quasi-static, quasi-dynamic and dynamic compression tests have been performed on a nitrogen alloyed austenitic stainless steel. This alloy achieves a high hardening modulus and a good ductility at all strain rates. In addition, this ...

This paper describes the implementation of a new material model into LS-DYNA version 960, LSTC (1-4), a material model capable of predicting the TRIP-effect of HyTensX for different forming operations in different temperature ...

The Crash Simulation of Magnesium Structures with Finite Element Methods demands the use of suitable material and failure models. An associated plasticity model describing the complex asymmetric yield behaviour in tension and ...

The Hill-Ogden elastic constitutive equation for incompressible and compressible rubber-like materials is presented. The derivation and computer programs to determine the material constants for these equations from uniaxial and ...

Presented is a theoretical description and computation method to calculate configurational forces in the context of the finite element method. We take fully 3D-case dynamics and large deformations in hyper-elastic materials into ...
