Progressive damage visualization and tensile failure analysis of three-dimensional braided composites by acoustic emission and micro-CT

Tensile failure and damage visualization based on progressive damage mechanics of three-dimensional braided composites were investigated. The complementary nondestructive testing technology combining acoustic emission with X-ray micro-computed tomography was used to analyze signal parameters, mechan...
