| This study is mainly based on an original approach of the specific problem of finite element modelisation of frictional contact usually met in the metal forming field. This particular phenomenon, actually present in transforming machines like presses, is applied here for hyperelastic materials.; The new tools used to treat the problem are Visual C++ and Diffpack. Diffpack, which is an object-oriented software, present the capacity to reduce the time to write and debug programs with the existence of powerful tools such as advanced abstractions and an interesting graphical environment. Those tools made possible, on one hand the implementation of the hyperelastic constitutive law for compressible materials, applicable in 3D and plane strain, and incompressible material, applicable in 3D, plane strain and plane stress, with the neo-Hookean formulation, on the other hand, the implementation of 2D contact with element Q4 and 3D contact with element H8. |
