High-rate mode II fracture toughness testing of polymer matrix composites – A review
Source abstract
Abstract
Abstract Composite materials are often subjected to mechanical impact causing delamination. For quasi-static loading, measuring the mode II fracture toughness has been standardized. However, for high-rate loading, additional challenges arise. Consequently, no standard test has yet been defined for measuring the mode II fracture toughness under high rates of loading. This article therefore reviews candidate tests for measuring the high-rate mode II fracture toughness. Strength and weaknesses of different specimen designs and test setups are shown. The different approaches are compared and recommendations are provided for measuring the mode II fracture toughness of composites under high rates of loading. The Transverse Crack Tension test has been identified as a promising approach to measure the high-rate mode II fracture toughness.
