Abstract

Model composites comprising of alternate layers of steel plates and epoxy adhesive were tested in compression to analyze the initiation of plastic microbuckling. Analysis of microbuckle initiation from a finite region of imperfection was performed by using a specimen containing a patch of waviness. The early stages of microbuckle growth were captured on video, confirming the mechanism of initiation and growth assumed by theoretical models. Results indicated that microbuckle propagation direction was locked at an early stage, adopting inclination angles similar to engineering composites.
