چکیده

The growth of transverse cracks in a composite layer is investigated using the semi-analytical high-fidelity generalized method of cells to represent a repeating unit cell of the composite. This method discretizes the domain into a number of subcells, each of which is occupied by a constituent of the composite. A non-linear displacement field approximation is used within each subcell, and displacement continuity and traction continuity are enforced, on average, at each subcell interface. Discontinuities are introduced at the subcell interfaces through the evolving compliance interface model. In this model traction and separation are related via a time dependent parameter. The predicted response for two simple examples of composite micro-architectures is presented and discussed.

Modeling of Interphases in Fiber-Reinforced Composites Under Transverse Loading Using the Boundary Element Method

In this paper, interphases in unidirectional fiber-reinforced composites under transverse loading are modeled by an advanced boundary element method based on the elasticity theory. The interphases are regarded as elastic layers between the fiber and matrix, as opposed to the spring-like models in the boundary element method literature. Both cylinder and square unit cell models of the fiber-inte...
