Evaluation of quasi-static indentation response of superelastic shape memory alloy embedded GFRP laminates using AE monitoring

In this paper, the potential of superelastic shape memory alloy (SE-SMA) wire embedded architectures to increase quasi-static indentation properties a laminated glass/epoxy composite material was evaluated. Three types SE-SMA configurations namely straight independent, meshed and anchored wires were in laminates via vacuum bag resin infusion technique. Throughout investigation, changes behavior allied damage mechanisms due these embedments compared with homogenous laminates. Real time acoustic emission (AE) monitoring technique employed characterize profile different specimens during tests. The experimental results showed that play vital role increasing penetration resistance by enhancing redistribution load all across particular, restricted an indenter delayed critical fiber fracture unlike homogeneous wired ones, whereas further extensive SMA/matrix pull-out, ones provided most excellent balance among rigidity, rear face breakage, pull-out. Straight, increased load-carrying capacity approximately 31%, 79%, 100%, respectively, comparison ones.
