摘要
本文在总结前人工作的基础上，采用严格的数学推导，针对三维变形过程，建立了空间任意形状的弹性曲杆在三维变形过程中的曲率－位移关系的新方法。文中的典型算例，显示了本文建议的方法的合理性与有效性。本文的工作，为空间曲梁单元的应变－位移表达式的建立工作。
Based upon a breif review of the existing investigations and a vigorous derivation, a curvature displacement relationship for an arbitrarily shaped,elastic, and curved bar in a three dimensional deformation process is obtained. A numerical example is given to demontrate the validity and effectiveness of the approach.This work provides a reliable foundation for establishing strain displacement relationships in curved element formulations of spatial beams.
