In this modified model, the effect of the stress concentration on the end stress in the fiber end region is considered, the average matrix strain is used to substitute for the so-called far field strain in the previous shear lag model. The change of the deformation states from elasticity to plasticity is considered and the interfacial shear stress and fiber axial stress are derived.

修正的模型合理考虑了纤维根区域应力集中对根应力的影响;用基体平均应变代替了经典剪切滞后模型中的远场应变;考虑了基体变形状态从弹性到塑性的变化,给出了塑性区上的表面剪切应力和纤维轴向应力的表达式。
