论文简介如下：
Puck criterion, a transverse failure criterion for composites, has more applications in engineering, but the empirical nature of its mathematical expression and the complexity of its parameters hinder its further development. In this work, a failure function is proposed based on the Puck hypothesis. According to the parameters of composites in special states, two modes of transverse tension and compression are distinguished, the pending coefficients in the failure function are derived, and then a transverse failure criterion for composites is formulated. The proposed criterion was evaluated experimentally in terms of envelope curves and off-axis strength using the existing data in the literature, and was compared with several other criteria. The results show that the proposed criterion is in good agreement with the experimental data, and its prediction accuracy ranks high among several criteria, demonstrating the rationality of the proposed criterion. Additionally, the effect of material parameters on the proposed criterion is analyzed and the results show that changes in transverse tensile and compressive strength can change the strengthening effect of transverse compression against in-plane shear, while changes in in-plane shear strength cannot change the strengthening effect. This work provides a correction method for the Puck criterion, which has a more rational mathematical expression with fewer parameters and can be used in the design of engineering composite structures, which has significant design reference value and theoretical significance.
