Meshless Local Petrov-Galerkin Method for Elasto-Static Analysis of Thick-Walled Isotropic Laminated Cylinders
In this paper, one of the simplest and most regular members of the family of the Meshless Local Petrov-Galerkin (MLPG) methods; namely MLPG5, is applied to analyze the thick-walled isotropic laminated cylinders under elasto-static pressure. A novel simple technique is proposed to eliminate a very important difficulty of the meshless methods to deal with material discontinuities regarding to the...
متن کاملDisplacements and Stresses in Pressurized Thick FGM Cylinders with Varying Properties of Power Function Based on HSDT
Using the infinitesimal theory of elasticity and analytical formulation, displacements and stresses based on the high-order shear deformation theory (HSDT) is presented for axisymmetric thick-walled cylinders made of functionally graded materials under internal and/or external uniform pressure. The material is assumed to be isotropic heterogeneous with constant Poisson’s ratio and radially varyi...
متن کاملAn Exact Elastodynamic Solution for Func-tionally Graded Thick-Walled Cylinders Subjected to Dynamic Pressures
In the present paper, an exact solution for transient response of an infinitely long functionally graded thick-walled cylinder subjected to dynamic pressures at the boundary surfaces is presented for arbitrary initial conditions. The cylinder is assumed to have a plane-strain condition and the dynamic pressures are assumed to be imposed uniformly and axis...
متن کاملHodograph Method of Nonlinear Stress Analysis of Thick - Walled Cylinders and Spheres , including Porous Materials
AbstraetA new method is developed, analogous to a hodograph method, for the nonlinear finite strain and stress analysis of thick-waged cylinders and spheres under internal and external pressure. The problem is reduced to solving a single ordinary differential equation of the first order. It is applicable to plastic or elastic materials. The case of porous cylinder with fluid seepage is also dis...
متن کاملModeling of Steady State Creep in Thick-Walled Cylinders under Internal Pressure
Abstract—The present study focused on carrying out the creep analysis in an isotropic thick-walled composite cylindrical pressure vessel composed of aluminum matrix reinforced with silicon-carbide in particulate form. The creep behavior of the composite material has been described by the threshold stress based creep law. The values of stress exponent appearing in the creep law were selected as ...
