On the deformation of layered composite arches using exponential shear and normal deformation theory

Abstract

Abstract. In the present study, the stresses and displacements are analyzed for layered composite arches of various lamination schemes subjected to uniformly loading. The present work is majorly highlighted the effects of transverse normal stress and transverse normal strain using exponential shear and normal deformation theory (ESNDT). Governing equations are derived using Hamilton’s principle with application of Navier’s method subjected to simply supported end conditions. Present theory is free from use of any shear correction factor and it satisfies the zero traction free end boundary condition at the top and bottom surfaces of the layered composite arches. In the present work symmetric and antisymmetric lamination scheme have been studied to obtain the numerical results for four layered composite arches and is validated through results available in prior literature.
