3D桁架结构失效分析
Abstract-In general, the progressive failure analysis of space truss systems can only be adequatelyevaluated with both material and geometric nonlinearities considered. This paper utilizes constitutiverelationships to provide the fundamental modeling of elastic and inelastic member behavior, coupled witha geometrically nonlinear finite element model. Modeled member material behavior modes include:buckling, yielding, inelastic post-buckling, unloading, and reloading. Geometric nonlinearity is based oniteratively correcting the linearized updated Lagrangian space truss displacement equations. Interactionof the nonlinear loading behavior results in structure force redistribution which can lead to memberfailure, unloading, or reloading. Such behavior can lead to the progressive failure of a space truss structure. The developed model traces the sequence of localized buckling, yielding, and inelastic member response.Results are presented to demonstrate model capabilities for representing the nelastic, progressive failureresponse of space truss structures. 本站免费提供《3D桁架结构失效分析》下载，我们己经对《3D桁架结构失效分析》进行全面的整理检查，以保证您安全的下载《3D桁架结构失效分析》，如果下载的压缩文件需要密码那就是本站的网址 http://www.xiaozhibei.com，3D桁架结构失效分析的文件大小为778 KB，本站还有大量关于结构论文,结构论文方面的资源提供下载哦，可以多找找。为下次能方便快速的找到本站，记得收藏我们的网址（http://www.xiaozhibei.com）哦！
