| Abstract: | To analyze the response of laminated composites under low - velocity impact, a finite element analysis model is established. In order to improve impact resistance of laminated composites, a technique of laminatedtoughening is adopted and ANSYS/LS-DYNA is utilized to simulate the damage process of laminated-toughened composites under impact load. Then toughening project is confirmed. It gives a theoretical reference for designing highly-effective toughening structure and the selective toughening. |
