基于MAT_58模型的碳纤维增强复合材料仿真参数捕捉与验证
Parameters calibration and validation of carbon fiber reinforced composite based on ∗MAT_58 model
摘要
Abstract
It is of vital importance to predict the failure behavior of fiber reinforced composite laminates in engi-neering applications.In this paper,the parameters of material model ∗MAT_58 in LS-DYNA of a type of carbon fiber reinforced composite laminate were calibrated and validated,by using a universal electronic test machine and a drop-weight impact test machine.The results show that:the physical meaning of ∗MAT_58 parameters are speci-fied by single element test;the effective failure strain is equals to 0.56 for 2 mm rectangular element by the double edge notched tension experiments combined with the Bazant crack band model;the peak force of the drop-weight impact experiment is highly sensitive to ERODS,the force-displacement curve of the experimental and simulation curves is in good agreement,with a minimum peak force error of 5.22%,which proves the effectiveness of ERODS;the fiber direction strength has the strongest effect on the mechanical response behavior during drop-weight impact,followed by in-plane shear strength and the matrix direction strength.关键词
