COMPARISON OF IMPLICIT AND EXPLICIT ALGORITHMS OF FINITE ELEMENT METHOD FOR THE NUMERICAL SIMULATION OF HYDROFORMING PROCESS

Abstract

This paper deals with numerical simulation possibilities of a hydroforming technology in production of a flow solar absorber with structured surface in asingle technological operation.An austenitic stainless steel X5CrNi18-10 is used as a material for the production of the flow solar absorber. In the theoretical chapters, a comparison between static implicit and dynamic explicit algorithms of finite element method (FEM) is performed. Experimental part of the paper includes creation of geometrical, material and computational models for the explicit and the implicit solution in software ANSYS Workbench Static Structural and ANSYS LS-DYNA. Finally, due to evaluation of the experiment and FEM results, the comparison between the implicit and the explicit theoretical solution of a formed part thickness is performed.
