- Abstract
- The model of thermomechanical behaviour of spatially reinforced expanded plastic is offered. On the basis of power criterion of equivalence and the kinematic assumptions about connection averaged deformations of such composite with deformations of phases of a composition thermomechanical characteristics of an equivalent material are certain. It is shown, that on the basis of the gained equations it is possible to determine the is intense-deformed conditions in all phases of a composition, using known averaged deformations and temperature in a composite that has basic value at calculations of the reinforced expanded plastic with use of structural theories of strength. The comparative analysis of desing characteristics with experimental data and with results of calculations by other techniques is lead.
