Study on simulation of near- and on- edge low-velocity impact damage of GFRP laminates

Abstract

Abstract: The near-edge and on-edge impact have a great influence on the residual strength of the composite material. Based on the three-dimensional Hashin failure criterion with stress description, combined with the improved Camanho degradation scheme, considering the impact damage of the test piece by the impact contact time, with the aid of ABAQUS to simulate the near-and on-edge impact damage of the glass fiber reinforced epoxy resin matrix composite (GFRP) laminate. At the same time, the Cohesive element is adopted to simulate the interlayer interface, and the impact process is simulated through the improved Vumat subroutine. The simulation results and the test results are compared and analyzed to verify the correctness of the model and the adapted subroutine. The results show that the non-linear reduction Vumat subroutine can predict the main characteristics of the laminate the near-edge, the on-edge impact damage, and the time-contact force curve more effectively compared with the direct reduction scheme. The near-edge and on-edge impact damage characteristics are quite different from the dynamic response.

Key words: composite laminates, near-edge impact, on-edge impact, finite element analysis, progressive damage
