Abstract
An efficient Higher order zigzag theory (HOZT) is proposed in this paper for analysis of laminated composite singly curved shell structures acted by point load on surface. The formulation includes effects of transverse displacement during analysis. Constant transverse displacement is assumed in face sheets while parabolic variation of transverse displacement field is assumed for central layer. Nine noded C0 finite element (FE) with eleven degrees of freedom per node is used for carrying out solution. Stress continuity at interfaces and zero stress condition at top and bottom face of shell are also included during formulation. A number of problems are solved for cylindrical shell panels subjected to point load is analysed. Present results are found in accordance with results those already available in literature.
