Comparative study of tensile behaviour for layered polymeric composite materials

Abstract

In this paper we present a comparative study on tensile failure behavior of polymer stiffened composite shell structures, using infrared thermography and finite element analysis through the ABAQUS 6.13 program. The establishment of the distortion of some rectangular shaped specimens was followed. In these specimens a hole with a diameter of 15 mm was applied centrally. By means of infrared thermography, was studied experimentally the variation of the deformations over time, depending on the stress force and the evolution of the thermal field in the crack area. Simulation models of failure behavior have been performed, which have been validated by experimental results.
