Originální abstrakt
The main target of the papaer is to present ideas behind a computational tool oriented toward adaptive nonlinear simulation driven by spatially varying model properties which is currently under development by authors. In particular, we focus on detailed tracing og the evolution of damage or other nonlinear phenomena during loading of structure with varying properties by nonlinear finite element method with mesh refinement/coarsening in highly/low stressed or damaged regions. We have developed the major ingredients of the algorithm and we present the current stage of progress on the computational platform in this paper. The computationsis illustrated on a simple one-dimensional example involving a bar made of plastic material with hardening under uniaxial tension.
