The paper presents elements of balance laws of continuum mechanics necessary for proper modelling of cooking vessel. The problem at hand must deal with multiphysical behaviour that involves both thermal and mechanical model. Coupled nature of the problem is solved by the separation of problem into two sequential steps. First step is the thermal step that gives temperature distribution throughout the cooking vessel. Upon calculation of temperature field, stresses are calculated. The mechanical phase involves calculation of permanent strains. Upon definition of physical model, constitutive model is briefly presented. The proposed procedure is verified on the one geometry of a cooking vessel.
