Abstract :
In this work both theoretical and experimental investigation was carried out to study the effect of residual stresses on the vibrational characteristics of plates with spot welded stiffeners at different boundary conditions. Expressions of the exact frequency equation were derived. Finite element modeling (FEM) was adopted to predict the tendon force produced due to spot welding and to find the natural frequencies at different modes. Different experimental models were tested to backup the results obtained theoretically. It was found that both theoretical and experimental results are in good agreement.
