On a computational approach to multiple contacts / impacts of elastic bodies

Autor: Jiří Vala, Václav Rek

Publikováno v: Programs and Algorithms of Numerical Mathematics 21.

The analysis of dynamic contacts/impacts of several deformable bodies belongs to both theoretically and computationally complicated problems, because of the presence of unpleasant nonlinearities and of the need of effective contact detection. This pa

On automation of XFEM computations considering general shapes of cracks in terms of the stress analysis of spatial structures

Autor: Václav Rek, Jiří Vala, Michal Jedlička

Publikováno v: Procedia Structural Integrity. 23:445-450

This paper pays attention to the automation of basic linear analysis of structures compound from brittle or quasi-brittle materials using the extended finite element method (XFEM) with extrinsic enrichment functions in the form of signed distances, u

Parallel Computing Procedure for Dynamic Relaxation Method on GPU Using NVIDIA's CUDA

Autor: Václav Rek, Ivan Němec

Publikováno v: Applied Mechanics and Materials. 821:331-337

This paper introduces a procedure for parallel computing with the Dynamic Relaxation method (DR) on a Graphic Processing Unit (GPU).This method facilitates the consideration of a variety of nonlinearities in an easy and explicit manner.Because of the
