Numerical Study of CFRP-Bonded Pressure Pipes Subject to Impact Load

Abstract:

A numerical approach is carried out to investigate the dynamic behavior of the CFRP strengthened pressure pipes subjected to impact load. In the FE analyses, Johnson-cook model is used to simulate metal subjected to large plastic strains and high strain rates, the fluid and pipe interaction is modeled by the surface-based fluid cavity to include the coupling effect between the deformation of the pipe and the internal pressure. Besides, the Hashin damage model is used to predict the damage of CFRP. The objectives of the numerical simulations are to capture the measured forming and crash history of the CFRP strengthened pressure pipes and gain an insight into the dynamic behavior of CFRP strengthened pressure pipes subject to impact load. The effects of internal pressure and the thickness of the CFRP are investigated, providing a detailed understanding of parameter sensitivity.
