| 摘 要： | 考虑横向剪切变形的任意四边形八结点弹性地基板单元是将Mindlin中厚板理论和Winkler假定相结合,并考虑地层与结构相互作用提出的。利用通用有限元软件ABAQUS所提供的用户自定义单元(UEL)接口,编制相应的接口程序,将此弹性地基板单元引入ABAQUS中,供其主分析模块调用计算。通过算例对所开发单元进行了验证,结果表明,本文所开发的弹性地基板单元是正确的、可靠的,具有较高的计算精度。同时,所提出的二次开发研究思路具有普遍性,对自定义单元的程序研制具有一定的参考价值。

| Abstract: | The quadrilateral element of eight nodes for plate bending considering the transverse shear deformation is based on the Mindlin plate theory, Winkler assumption and the interaction between the formation and infrastructure. According to interface requirements for user-defined element (UEL) of ABAQUS, the corresponding UEL interface codes of ABAQUS are programmed, which will be called by the main analytical module of ABAQUS. Numerical simulations of elastic foundation plate tests are performed to verify the c... |
