A stochastic finite difference approach based on stochastic finite elements is proposed for heat and mass transfer modeling. Porous structure with random material properties is investigated. The theoretical formulation of the problem is described. A system of partial differential equations is obtained and solved for first two probabilistic moments of the random temperature field. Example of stochastic...
The purpose of the paper is to discuss the hardening problems in materials. Kinematic and isotropic hardening are considered. The paper has a review character.
Dokonano analizy przepływu ciepła i ruchu wilgoci w porowatej strukturze. Opisano podstawy teoretyczne problemu. Przedstawiono system równań rządzących procesem przepływu ciepła i ruchem wilgoci. Praca ma charakter przeglądowy.
The purpose of the paper is to compare two basic yield criteria met in engineering mechanics i.e. Huber-Mises and Treska. The various forms of the yield locus are presented and discussed. The paper has a review character.
