A Model for Load-Transfer from an Embedded Fiber to an Elastic Matrix
Abstract
A model is presented for approximating load-diffusion from axially loaded fibers embedded in elastic matrices. The fundamental elastostatic solutions used are for a point force and point dilation in either a fully- infinite or semi-infinite space. Tangential tractions across the fiber-matrix interface are included explicitly in the analysis. The model is applied to the three-dimensional analogs of Melan's first problem and Reissner's problem and comparisons are made with exact results in the case of the former to help establish the validity of the model. The ability to analyze load-transfer in fiber-matrix systems which are illustrative of those that exist in fiber- reinforced materials is fundamental to the study of how such materials behave in application. Our ability at present, however, to rigorously solve such problems in the realm of three-dimensional elasticity is limited to a few isolated results involving infinite fibers bounded along their entire length to full- infinite matrices.
