摘要

A novel method for the mechanical simulation of linear and nonlinear Timoshenko-beams has been presented.The beam strains are based on a kinematic assumption where the shear deformation and rotational are considered.Applying the isoparametric concept the kinematic quantities are approximated using NURBS(non-uniform Rational B-spline)functions.This numerical simulation can be called as isogeometric analysis,which can improve the efficiency in CAD(computer aided design).Furthermore,an efficient Code has been developed and the results for two numerical applications are given in the end.
