单向纤维增强复合材料板的强度准则研究一般可分为:1)提出合理物理假设,建立强度准则的数学表达式;2)用实验方法来直接建立单向板在应力空间中的破坏曲面;3)混合使用前两种方法,提出半经验形式的准则。
The research on strength criterion of unidirectional fiber-reinforced composite sheet can be generally divided into: 1) putting forward reasonable mathematical assumptions and establishing the mathematical expression of strength criterion; 2) using experimental method to directly establish the failure surface of unidirectional board in stress space; 3) Mixed use of the first two methods, put forward the semi-empirical form of the guidelines.
