Abstract: This study proposed a finite element simulation method to analyze the progressive failure of fiber-reinforced polymer (FRP)
reinforced steel component under low-velocity impact. In this method, the Johnson-Cook model and fracture criterion were
used to consider the strain rate effect of steel; additionally, a VUMAT subroutine was proposed to discuss the 6 initial
failure modes (fiber tension/compression failure, matrix tension/compression failure and in-layer tension/compression
delamination failure) and damage evolution of FRP. In order to verify the simulation results, a series of axial low-velocity
impact tests on GFRP-reinforced circular steel tube were performed, the comparative study confirmed that the simulations
were in good agreement with the test results. Besides, the advantages of proposed VUMAT subroutine were made obviously
by comparing to the Puck criterion, the Hashin criterion, and the Chang-Chang criterion.
