Modelling of internal heat and mass transfer and stress-strain state in composite shells under local heating

Model of thermomechanical processes in thin composite shells under high temperatures with effects of thermal decomposition was developed. This model describes interlaminar and transverse stress in the shell as well as a change of composite properties under heating.
Numerical technique for solution of internal heat and mass conduction problem and thermomechanic of thermodestructing composite shells was developed. The technique is based on a finite element method procedure for a shell theory problem and finite difference method in combination with step-by-step finite difference method for a system of equations of internal heat and mass conduction.
