In this paper we submit a procedure for determination of the ranges in which physical phenomena and fracture mechanisms arise when energy fluxes act on thin-walled deformable elements of structures built from composite materials. The results can be used to shape computer models that adequately describe the physicomechanical and gasdynamic processes accompanying high-intensity exposures. Certain problems of the action of energy fluxes on plates made from composite materials are stated and solved as examples on the basis of the approaches proposed here.
