There are numerous studies on the compound structures, made of two dissimilar materials, joined by using modern welding techniques, which find applications in many fields of engineering because of achieving a better response under various loading conditions. The mechanical and thermal buckling behavior of compound stepped structural members, like two stepped circular plates, consisting of two concentrically placed different materials, is of particular interest to engineers in design the modern structures. These have a wide range of applications owing to their higher values of strength to weight ratio, compared to isotropic plates.
In this paper, the influence of the thickness ratio and the radius ratio of the two concentric steps on the buckling of stepped compound circular plate with the material combinations of aluminum, titanium, steel and copper, for simply supported and clamped boundary conditions, are studied by using the Rayleigh - Ritz (RR) method. The results show the effect of the material combinations on the mechanical thermal buckling load parameters of the stepped compound circular plates with respect to the thickness and the radius ratios.

The aim of this study is to estimate numerically the beneficial effect of adding patches for repairing cracks using the finite element method. The Stress Intensity Factors (SIFs) are obtained using patches. It is observed that with patch on the cracks there is a reduction of stress intensity factors. The effects of the adhesive, patch and plate properties on the rate of reduction of the stress intensity factors is highlighted. In this work, FRANC 2D/L has been used as an analysis tool to compare the SIF values for the plate with or without patches.Keywords
