The aim of this test case is to validate the following functions:
The simulation results of SimScale were compared to the numerical results presented in case B of [SDNV103]. In addition to the quadratic mesh consisting of prisms and hexahedrals described in [SDNV103], the linear hexahedral mesh was also used.
Tool Type : Code-Aster
Analysis Type : Dynamic (nonlinear elastoplastic)
Mesh and Element types :
|Case||Mesh type||Number of nodes||Number of prisms||Number of hexahedrals||Element type|
|(A)||linear prisms and hexahedrals||764||120||481||3D isoparametric|
|(B)||quadratic prisms and hexahedral||2861||120||481||3D isoparametric reduced integration|
|(C)||quadratic prisms and hexahedral||2861||120||481||3D isoparametric standard|

Initial Boundary Condition:
Comparison of the displacement Dx and Dy computed on points J and L respectively at time 9e-5 obtained with SimScale and the results presented in case B of [SDNV103].
