Abstract

Journal of Composite Materials, Ahead of Print.
A numerical methodology is proposed to determine the 3D failure criteria of directional composite joints, accounting for both in-plane (in-/off-axis) and out-of-plane behavior. The approach involves simulating standard composite joint characterization ...
