Structure Modeling of the Strength Criterion of Periodic Composites Under the Complex Temperature-Force Loading

The model of the strength criterion of doubly periodic unidirectional composites (CM) under the complex temperature-force loading is worked out on the base of structural approach. The investigation of the effect of temperature on the strength properties of CM is analyzed using the suggested model. The condition of averaging of microstresses on the volume of representative elements and the condition of continuity of displacements at the interfaces between them are fulfilled.
