Low Velocity Impact (LVI) Simulation of a CFRP Ply-Drop Laminates: A Numerical Analysis
摘要
Carbon Fiber Reinforced Polymer (CFRP) composites are well established in aircraft, aerospace and automotive industry due to their lightweight structure and robustness. Generally, in uni-directional (UD) composite laminates the mechanical properties depend of fiber orientation, the number and the thickness of the plies and the stacking sequence [1], Fig. 1. In continuous fiber laminates the prediction of failure is dependent on the fiber orientation and the failure criteria that are adopted.
