FEM model and experimental measurement of clinched joint

This work describes creation of FE model of clinched joint and brings information about its verification with help of experiment. Also the sensitivity of the simulation model to the selected parameters (size of the model and coefficient of friction) and boundary conditions is studied so that the model is close to the reality. Deformation and uniaxial stress near the joint obtained with help of strain gauge is the output from the unidirectional, nondestructive test. Comparison of two values of stress in the chosen place obtained by experiment and FE simulation is the principle for verification of FE model and its adjustment. Based on the results it can be said that the FE model corresponds with the reality with the desired accuracy. (paper)
