Vibration behavior of different types of porous functionally graded (FG) conical sandwich shells are investigated based on a modified high order sandwich shells theory for the first time. Sandwich shell includes FG face sheets covering a homogeneous core and the second one includes homogeneous face sheets and a FG core. Power law rule modified by considering two types of porosity distributions ...
Abstract The influence of single and multiple imperfection cases on the load carrying capacity mild steel cone subjected to axial compression was considered through numerical simulation in current paper. Three different techniques were considered, which are: i) uneven length (sinusoidal/square waves), ii) crack, iii) indentation (SLI) imperfection. Abaqus 6.19 FE used carry out simulation. comp...
As a major structural dynamic criterion in designing thin shells, the fundamental frequency is maximized for a specified total structural mass. The general optimization problem of metallic conical shell structures with clamped / free ends has been treated formally among all other types of boundary conditions. Both stiffened and unstiffened constructions are examined with the effective design va...
