This paper investigates the free edge effect on the stress field of a carbon fiber, which is embedded into an epoxy matrix. The fiber is assumed to possess cylindrical symmetry and to be transversely isotropic. The matrix is assumed to be of an isotropic material. The stress field is induced by a uniform tension applied on the matrix at points far away from the fiber surface. The displacement a...

This paper shows the coordinates influence on singularity of a three degree-of-freedom structure, namely, three-Universal-Prismatic-Spherical (3-UPS) parallel manipulator. Rotational coordinates, which are chosen to define the orientation of the platform, affect the singularity of the manipulator. Euler parameters, which don't have any inherent geometrical singularity are utilized, however they...

The present paper deals with the mixed mode fracture analysis of a weakened orthotropic half-plane with multiple cracks propagation. The orthotropic half-plane contains Volterra type glide and climb edge dislocations. It is assumed that the medium is under in-plane loading conditions. The distributed dislocation technique is used to obtain integral equations for the dynamic problem of multiple ...

Problems of stress singularities in single or multi-material corners have been addressed by many authors over the years. Most presented closed-form corner-eigenequations for special cases, and often there is no easy way to check if solution correct. In this work, we present a general computational tool that can solve different cases singularity problems under generalized plane strain. The semi-...

An analytical method to find the flow generated by the basic singularities of Stokes flow in a wedge of arbitrary angle is presented. Specifically, we solve a biharmonic equation for the stream function of the flow generated by a point stresslet singularity and satisfying no-slip boundary conditions on the two walls of the wedge. The method, which is readily adapted to any other singularity typ...
