Abstract
On the basis of a minimax criterion and stress intensity factor minimization, the optimal preload is determined for the case of elastic fibers fit into a doubly periodic system of holes in an isotropic elastic binder. A selection criterion is proposed for an interference fit that prevents the fracture of a composite reinforced with unidirectional fibers and ensures optimal stress distribution.
