Method for Monitoring In-Plane Shear Modulus in Fatigue Testing of Composites

Source

A method was developed for nondestructive intermittent monitoring of in-plane shear modulus of composite specimens undergoing fatigue loading. A modified three-rail shear fixture was designed for easy mounting and disassembly. The shear strain is measured with an extensometer attached to the rails of the fixture. Modulus results were in excellent agreement with independently measured values. The method is ideal for studying damage development, since the in-plane shear modulus is sensitive not only to transverse matrix cracking but also to longitudinal cracking and delamination.
