ABSTRACT
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.
KEYWORDS
