TITLE: Modeling and Simulation Strategies for Thickness Reinforced Composites
DATE: Monday, July 24, 2017
TIME & LOCATION: 9:00 AM EB3 – 3115
ABSTRACT:
Delamination has been identified as a dominant failure mode for laminated composites subjected to impacts. Experimental tests have shown that 3D woven composites and z-pin reinforced composites have higher delamination resistance than traditional laminated composites. Due to additional through the thickness reinforcement (TTR), damage and failure mechanisms of these composites are considerably different. Capturing all the details of different failure modes through simulation is computationally expensive and impractical. In my study, woven and z-pin reinforced composites are evaluated separately using different modeling and simulation strategies. Equivalent material model is developed which can capture the response of TTR composites without additional computational cost. Reliable and efficient finite element simulations can provide a great tool for evaluating the composite response and reduce the time and costs by avoiding repetitive experimental tests. Such efficient modeling techniques can reduce the time required to implement an innovative design concept into a final product.
