Abstract

Load-controlled tension-tension cyclic tests on continuous fiber sheet molding compound (CSMC) composite-metal bolted joints have been performed. The test results show that both failure mode and stress-life data depend strongly on whether the width of the specimen is larger or smaller than the clamped area. Based on the observed failure modes in a single bolt pattern, a stress-life model is proposed. Limited data for multiple bolt patterns are reasonably consistent with the failure model.
