Compression Failure Model of Fiber Reinforced Composite Materials

Due to the complex compression failure process of fiber composite materials, especially the direct bearing situation of the composite material end face, it is quite difficult to accurately predict it. At present, the design of composite material compression performance mainly considers a large safety factor, and a compression failure assessment method that can meet the needs of reliable engineering applications is still a challenge and a key issue that the engineering community urgently needs to solve. This article reviews the widely studied shear type buckling model, extensional type buckling model, matrix strain failure theoretical model, matrix shear failure theoretical model, interlayer shear failure theoretical model, elastic micro buckling model, plastic micro buckling model, three parameter model, fiber microbuckling finite element model and ply mesobuckling finite element model of fiber reinforced composite materials that have been publicly published in recent years, which were analyzed and summarized, providing reference for further in-depth research in the future.
