STUDY ON BEARING CHARACTERISTICS OF LAMINATED PLATE WITH SINGLE JOINT BASED ON PARAMETRIC METHOD

Abstract

Abstract: Three dimensional cumulative damage theory and Yamada-Sun failure criterion are used to simulate the failure process and load-bearing characteristics of laminated plate with single joint based on ABAQUS in this paper, and the simulation results are in good agreement with the test results. A parameterized method of 3D finite element modeling of laminated plate with single joint is proposed with the help of Python language and self programming. This method can realize the automatic completion of the whole process from modeling to analysis to post-processing, which greatly reduces the time cost of early modeling. At last, the influence of geometric parameters, fastener parameters and load factors on the load-bearing characteristics of the laminated plate with single joint is studied. The results show that the load-carrying capacity of laminated plate with single joint can be effectively improved by choosing appropriate plate length, end distance to hole ratio, width to hole ratio, increasing hole diameter, hole roughness and bolt preload.

Key words: parametric method, laminated plate with single joint, three dimensional cumulative damage, bearing characteristics, composites
