The chapter deals with the problem of the interaction of multiple damage mecha-nisms in multilayered and sandwich structures subject to static and dynamic load-ing conditions. The effects of the interaction on the mechanical behavior of com-posite systems are studied by means of one-dimensional models based on particularizations of the theories of bending of beams and plates. The study shows that the interaction of multiple delaminations in laminated and multilayered sys-tems subject to out of plane loadings profoundly affects crack growth characteris-tics and different key properties; controlled delamination fracture, via material and structure design, can improve impact and damage tolerance and energy absorption.

Abstract

The chapter deals with the problem of the interaction of multiple damage mecha-nisms in multilayered and sandwich structures subject to static and dynamic load-ing conditions. The effects of the interaction on the mechanical behavior of com-posite systems are studied by means of one-dimensional models based on particularizations of the theories of bending of beams and plates. The study shows that the interaction of multiple delaminations in laminated and multilayered sys-tems subject to out of plane loadings profoundly affects crack growth characteris-tics and different key properties; controlled delamination fracture, via material and structure design, can improve impact and damage tolerance and energy absorption.
