Isogeometric analysis for 3D printed concrete monoclinic Timoshenko beam

Abstract

Anisotropy is one of the most important characteristics of 3D printed concrete. If material property is only symmetric on one plane, it is called monoclinic material, in which there are totally 13 independent elastic constants. In this paper, 3D printed concrete Timoshenko beam is analysed using isogeometric technique considering the monoclinic material property. Non-uniform Rational B-Spline(NURBS) functions are used as basis functions to integrate with computer aided design data. In addition, several numerical experiments are conducted to verify accuracy of the isogeometric analytical model. It is demonstrated that the proposed method in this paper can be widely used in analyses of 3D printed concrete monoclinic Timoshenko beams.
