Failure of composite materials at high temperatures and finite strains

Abstract

Elastomeric composite materials that are serviceable at high temperatures and finite strains are often used to protect load-bearing members of structures against the action of heat fluxes. Methods for the calculation of strain of elastomeric materials with finite strains at normal temperatures have been set forth previously. For the case of small strains, a model of strain and strength of polymeric materials can be used to predict their serviceability at high temperatures when thermal breakdown processes take place in the plates. In the present work, this model is extended to the case of finite strains.
