基于响应面法的复合材料连接结构可靠性分析
Application of response surface method on structural reliability analysis of pin j oint in composites
摘要
Abstract
Composite materials exhibit much more scattering material properties than metallic materials. The paper presents an application of weighted response surface method on structural reliability analysis of a composite pin j oint.A three-dimensional finite element model is used to perform the deterministic progressive failure analysis of composite pin j oint.The mechanical properties and ultimate strengths of one lamina are modeled as random variables and considered in the process of structural reliability analysis.A detailed study on the effect of different failure criteria and stiffness degradation rules is performed.This study shows that the combination of Olmedo-Santiuste failure criteria and Camanho-Matthews stiffness degradation rules produces the closest bearing strength result to experimental mean value.Another detailed study is also performed to investigate the effect of response surface parameter f . The results show that linear weighted response surface function with f=1 is capable of providing good approximations of statistical characteristics of the bearing strength of pin joints in composite laminates for structural reliability analysis.关键词
