TORSIONAL SHEAR STRESS IN PRISMATIC BEAMS WITH ARBITRARY CROSS-SECTIONS USING FINITE ELEMENT METHOD

Determining the shear stress of a structural element caused by torsion is vital problem. The analytical solution Saint-Venant only suitable for simple cross-sections. numerical method to evaluate complicated cross-sections indispensable. Many methods have been studied scientists. Among these studies, Gruttmann proposed an excellent method, which inherited theory. However, use isoparametric four-noded quadrilateral elements made not reach best optimization. objective this paper improve Gruttmann‘s using eight-noded elements. MATLAB language programming method. validated examples demonstrated that author’s more effective than
