摘要:
基于有限元分析软件ABAQUS内聚力单元,采用自定义材料(VUMAT)编译二维平面状态下弹塑性内聚力模型子程序.用所编写的弹塑性内聚力模型VUMAT子程序对薄板粘接结构的开裂进行模拟计算,并与双线性内聚力模型、多项式内聚力模型的VUMAT子程序模拟结果及实验结果进行对比分析.结果表明内聚力关系对粘接结构开裂过程的拉力变化影响较大,对不同胶体的粘接结构应选择相应的内聚力模型.
Abstract:
Based on the finite element analysis software Abaqus cohesion unit, a two-dimensional elastoplastic cohesion model subroutine was compiled by using a custom material (VUMAT) . Using the developed VUMAT subroutine of elastic-plastic cohesive force model to simulate the cracking of thin plate bonding structure, the simulation results are compared with those of the bilinear cohesion model and the polynomial cohesion model by using the VUMAT subroutine. The results show that the cohesion relation has a great influence on the tensile force of the adhesive structure during the cracking process, and the cohesive force model should be chosen for the adhesive structure of different colloids.
