Torsion in Microstructure Hollow Thick-Walled Circular Cylinder Made up of Orthotropic Material

In this paper, a numerical solution has been developed for hollow circular cylinders made up of orthotropic material which is subjected to twist using micro polar theory. The effect of twisting moment and material internal length on hollow thick-walled circular cylinder made up of micro polar orthotropic material is investigated. Finite difference method has been used to exhibit the influence o...

On Pressurized Curvilinearly Orthotropic Circular Disk, Cylinder and Sphere Made of Radially Nonuniform Material

A unified analysis is presented for the elastic response of a pressurized cylindrically anisotropic hollow disk under assumed conditions of plane stress, or a hollow cylinder under plane strain conditions, and a spherically anisotropic hollow sphere, made of material which is nonuniform in the radial direction according to the power law relationship. The solution for a cylinder under generalize...

Proposal for a Failure Surface for Orthotropic Composite Materials

Fracture Problems in Composite Materials

In this paper a series of fracture problems in composite materials are identified, their methods of solution are briefly discussed, and some sample results are presented. The main problem of interest is the determination of the stress state in the neighborhood of localized imperfections such as cracks and inclusions which may exist in the composite. Particular emphasis is placed on the evaluati...

Mathematical modelling of thermoelastic problem in a circular sector disk subject to heat generation

The present paper deals with the determination of temperature, displacement and thermal stresses in a circular sector disk defined as 0 ≤ r ≤ a , 0 ≤ φ ≤ φ0 < 2π, 0 ≤ z ≤ h under an unsteady-state temperature field, due to internal heat generation within it. The time dependent heat flux f1(φ, z , t ) is applied on the fixed circular edge (r = a ). For time t > 0, the boundary surfaces at (φ = 0...
