Strength and Failure Characterization of a Glass Fiber SMC-R Composite Under Biaxial Loads

M. URAPAKAM RAMAKRISHNAN, P. K. MALLICK

Abstract


Sheet molding compound composites containing randomly oriented short fibers (SMC-R) are among the most commonly used composites in the automotive and many non-aerospace applications. Many studies have reported the static and fatigue properties of SMC-R composites under uniaxial stress conditions. However, there are many applications in which they may be subjected to biaxial stress conditions and their biaxial properties have not been reported in the literature. The current study considers the mechanical characterization of a glass fiber SMC-R under biaxial loading conditions that generate various combinations of normal and shear stresses. It also includes a study on the damage development and failure prediction under biaxial loads.
