Metamaterial improved nonlinear ultrasonics for fatigue damage detection
TL;DR: In this paper, a bandgap metamaterial was developed to improve the accuracy and identifiability of the superharmonic features from fatigue cracks by eliminating the inherent nonlinear components in the nonlinear ultrasonic technique.

A simple method for determining the mode I interlaminar fracture toughness of composite without measuring the growing crack length
TL;DR: In this paper, a double compliant method was proposed to determine the fracture toughness of composite materials, which is nearly the same as that recommended by the ASTM standard, except avoiding measuring the growing crack length.
