The probabilistic approach for the estimation of vitality of the military protective thin shell constructions with damages from explosive devices using of calculable procedures of modern softwares of finite element analysis was created. The new probabilistic multiparametric model of shell surface damages from shock thermal influence of explosion and fragments of explosive devices was created. Based on the moment finite element scheme, a calculation model has been constructed for the analysis of nonlinear deformation and vibrations of composite multilayer shells of step-variable thickness under the action of thermomechanical loads. A new modification of a universal three-dimensional multilayer finite element has been created, the layer materials of which are unidirectional fiber composites.
