In-Plane Shear Properties of Laminated Wood from Tension and Compression Tests of Angle-Ply Laminates

Abstract

Experimental methods for the characterization of shear strength and stiffness of both wood-based and glass-based or carbon-based composite materials are highly contested because shear properties are difficult to isolate experimentally. A comprehensive literature review on the subject is presented, considering methods for both structural composite lumber and traditional composite laminates. The researchers present a novel method for calculating shear strength, stiffness, and interaction parameters of laminated wood-veneer panels by coupling experimental data from tension and compression tests of multiaxial laminates with an optimization routine for two failure criteria theories from the literature. Optimal shear parameters are reported for both theories.
