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.

单向纤维增强复合材料的优化设计

在极大极小值准则和应力强度因子最小化的基础上，对于弹性纤维装入各向同性弹性粘合剂中的双周期孔系统的情况，确定了最佳预紧力。为防止用单向纤维增强的复合材料断裂并确保最佳应力分布的干涉配合提出了选择标准。
