Elastic State of a Sliding Short Fiber Inclusion in a Three-Dimensional Matrix
- 26 Downloads
The three-dimensional problem of load transfer between an unbounded matrix and an arbitrarily shaped inclusion that are in sliding contact is solved using the theory of elasticity and the boundary-element method. The interface conditions are implicitly incorporated into a system of six boundary integral equations, which are regularized and discretized over a boundary-element mesh. A short cylindrical fiber with rounded ends is considered as an example of inclusion to study the contact forces on its surface and the displacements and stresses inside it in a matrix subject to uniform compression at infinity
