Testing for Tensile Rate-Dependence in Composite Laminates
Material properties at high strain rates are a necessity when designing composite structures subject to impact loads. This paper presents a method to test from quasi-static up to intermediate strain rates of 100 per second. A hydraulic pulse test bench is used where the actuator is connected to the specimen with some free-sliding movement to enable testing at constant velocity. Digital image correlation is used to measure the strain successfully up to the highest actuation speed.
