Garbatov, Y. and Guedes Soares, C. (2005), “Hot-Spot Stress Assessment of Longitudinaly Stiffened Dek Structure”, Proceedings of the Second International Congress on Mechanical and Electrical Engineering and Marine Industry (MEEMI´05), 7-9 October, Varna, Bulgaria, Vol. I, pp. 26-33
This work aims to perform a finite element stress analysis of a longitudinally stiffened deck and to evaluate the hot spot stress distributions and stress concentration factors. The analysis is performed for two structures. The first one is symmetric, having a transverse weld, and the second structure is unsymmetrical, having a transverse and partial longitudinal weld. The hot spot stresses and the stress concentration factors are evaluated at the places adjacent to the transverse weld. Both of shell and solid finite elements are used for modeling each of four sets of step changes of thickness of plates applying the finite element method.
