Abstract

The paper presents the finite element code LOGOS for high performance computing developed in Russian Federal Nuclear Center VNIIEF. Among other, its functionality intended to numerical analysis of quasi-static strength problems. The description of main procedures and algorithms that allow accounting both physical and geometrical non-linear effects and contact interaction, is given. At present, the code is tested and verified by a number of Russian key industrial enterprises. Results of numerical modeling of complex engineering constructions are shown that demonstrate robustness and applicability of code LOGOS to nonlinear analysis of models subjected to quasi-static loading.
