摘要

使用弹性理论的单元问题解决方案分析了复合纤维交叉增强胶粘剂的主要应变类型。结果表明，所有之前预测的纤维复合粘合剂局部应变的可能类型都在均质化理论的单元问题数值解中得到了揭示。粘合剂的局部应力应变状态在很大程度上取决于纤维的横截面形状。方形纤维的应力应变状态可以通过显式公式计算，而其他形状纤维的应力应变状态只能通过计算机估算。

Calculation of Stress-Strain State of Fiber Composite Adhesive

The main types of strain of an adhesive cross-reinforced with composite fibers is analyzed using a solution to the cell problem of the elasticity theory. It is shown that all previously predicted possible types of local strain of a fiber composite adhesive are revealed in numerical solutions to the cell problem of the homogenization theory. The local stress-strain state of the adhesive significantly depends on the cross-sectional shape of the fibers. The stress-strain state in the case of square fibers can be calculated either using explicit formulas, and the stress-strain state in the case of fibers of other shapes can be estimated only using a computer.
