MODELING OF THERMOMECHANICAL PROCESSES IN COMPOSITE SHELLS IN LOCAL RADIATION HEATING

摘要

A model of thermomechanical processes of composite thin-walled shells at high temperatures with account for thermodestruction effects has been developed. The model allows for interlayer and transverse stresses in the shell and variation of composite properties in heating. A numerical method has been developed for solution of problems of internal heat and mass transfer and thermomechanics of composite thermodestructing shells. The method is based on the finite element method for the problem of the theory of shells and the finite-difference method for the system of equations of internal heat and mass transfer.
