碳布增强木质层合板的有限元渐进损伤分析
Finite element progressive damage analysis for carbon fiber cloth reinforced wooden laminate
摘要
Abstract
In order to enhance the properties of composites,the carbon fiber cloth reinforced wooden laminate was taken as the sample plate,and a finite element progressive damage model was established. Both Hashin and BK failure criteria were taken as the failure judgment criteria,and the degradation method was used for the experimental analysis.In addition,the ABAQUS/Explicit software was used for the parametric modeling,and the damage of laminate under the low speed impact effect was forecasted and analyzed.The results show that compared with the delamination area of 0 layer laminate,the delamination area of carbon fiber cloth reinforced wooden laminate reduces about by 50%.The experimental and calculated values of impact contact force are in good agreement,which verifies the feasibility of degradation model and the validity of finite element model.关键词
