Thermal Influence on the Stiffness of Hybrid Metal-Composite Countersunk Bolted Joints

This paper presents the effects of temperature on the axial stiffness of a hybrid metal-composite countersunk bolted joint designed for the bearing failure mode. A detailed 3D finite element model incorporating geometric, material and friction-based full contact nonlinearities is developed to numeri...
