Abstract
Due to the different thermal expansion coefficients of composite materials and metal materials, the variation of ambient temperature changes the load transfer ratio of composite-metal hybrid joint structures. In this paper, the Finite Element Method (FEM) is used to study the combined effects of external load and temperature field on the load distribution of CFRP-aluminium alloy single-lap hybrid joints. The effects of the temperature rise and fall on load transfer are considered. The simulation results show that the most dangerous position and the load transfer ratio of the hybrid show significant joint changes after the combination of the temperature effect under the external load.
