纤维增强复合材料(Fiber Reinforced Polymer,FRP)因具有较大的比刚度、比强度、结构可设计性等优点而被广泛应用在航空、船舶、汽车、风电等行业中。随着复合材料在工程结构中的应用由次承力构件逐步扩展至主承力构件,疲劳破坏在复合材料结构中已逐渐显现,正成为制约其进一步应用的重要因素,因此复合材料的疲劳问题正成为使用者和工程设计人员十分关注的问题。对层合板的疲劳寿命展开预测是复合材料疲劳问题的基本研究内容之一,也是复合材料结构设计的重要工作之一。工程应
Fiber Reinforced Polymer (FRP) is widely used in aviation, shipbuilding, automobile, wind power and other industries due to its advantages of greater specific stiffness, specific strength and structural design. With the application of composite materials in engineering structures, the secondary load-bearing members are gradually extended to the main load-bearing members. The fatigue failure has gradually become apparent in the composite structures, which is becoming an important factor restricting its further application. Therefore, the fatigue of composite materials Is becoming a concern for users and engineering designers. Predicting the fatigue life of laminates is one of the basic research topics of the fatigue problem of composite materials, and it is also one of the important work in the structural design of composite materials. Engineering should be
