dc.description.abstractCrashworthiness has become an important aspect in vehicle design due to the stringent requirements on occupant safety under survivable accident scenarios. The uses of composite materials have increased due to their tailorability and high specific strength and stiffness. Variety of energy absorption devices have been investigated for their energy absorption characteristics. Literature suggests that corrugated beam geometry promotes stable crushing behavior and has the highest energy absorption capability. But a lack of consensus on the rate sensitivity of these devices exists and is mainly attributed to different material systems, specimen geometries, test apparatus used, etc. This experimental study addresses the progressive crushing of Newport NB321/7781 E-glass and Toray T700G/3900 plain weave fabric prepreg fiber-reinforced corrugated panel. The progressive crushing behavior is studied at quasi-static rates as well as dynamic loading rates up to 100in/s. Load rate effects, stacking sequence effects and laminate gross thickness effects on energy absorption of corrugated beams were investigated. The test data indicates that the specific energy absorption of corrugated beams is rate sensitive. Besides, modes of failure of corrugated beams were observed to be sensitive to test speed. Furthermore, stacking sequences of [0]n are superior in energy absorption compared to [45]n and thickness of the laminates were observed to affect the specific energy absorption.
