The stiffness of the car body becomes important due to the fact that it must keep the passenger's compartment undeformed even during severe operating conditions. Car body Tjoint is one of the main parts of car's body to properly support its function. Three different cases were applied to evaluate the influence of difference spot weld configuration to bending and torsional stiffness of car body T-joint. The stresses and the displacements were also deeply investigated. The maximum stress in longitudinal direction and due to moment reaches its peak on 55x15 spot weld configuration. The displacement increases as the spot weld distance widen. Both bending and torsional stiffness decrease as the spot weld distance becomes larger. © 2020 Institute of Physics Publishing.
