复合材料加筋板极限压缩承载能力可靠性分析
Reliability analysis of ultimate compressive strength for stiffened composite panels
摘要
Abstract
The progressive failure analysis method is utilized to predict ultimate compressive strengths of stiffened composite panels based on the user subroutine of Abaqus software in this paper .Numerical examples are shown that the relative errors of ultimate compressive strengths obtained by using the proposed method and the experimental data are 2 .53% and 1 .68% for samples 1 and 2 respectively .To reduce the computational efforts in the process of reliability evaluation ,the relationship between the buckling load and the ultimate compressive strength is used to establish the performance function ,only one time the ultimate compressive strength is analyzed in the process of reliability evaluation by using the proposed method .Numerical examples are show n that the relative errors of the proposed method and the classical reliability method are -1 .04% and -1 .01% for samples 1 and 2 respectively ,the ratios of the proposed method to the classical reliability method are only 1 .18% and 1 .66% for samples 1 and 2 in terms of the total computational time .关键词
