Calculation Model for the Analysis of Strength and Stability of Anisogrid Mesh Structures under Intensive Thermal Force.

The procedure for the numerical study of the stress-strain state and the stability of the mesh structures of polymer composite materials under intensive force and thermal effects is considered. A simplified mathematical model of the thermomechanical behavior of the mesh structure is proposed, taking into account the reversible and irreversible changes in the physicome-chanical properties of the material during heating. The design process of computational algorithms is described. [ABSTRACT FROM AUTHOR]
