Sažetak
This paper deals with the shear stress analysis of engineering beams with uniform cross-sections using finite element method. The analysis is based on special finite elements whose properties, like stiffness matrices as well as load vectors, are derived on the basis of their axial nodal displacements. From geometrical point of view there are 3-D finite elements, but according to the strain or stress tensor, there are 2-D elements. The mentioned stress analysis is independent of the cross-sectional member shape and the material properties .These elements are directed to shearing stress analysis due to Saint-Venant&#8217; s torsion and due to loading of a beam by shear forces. Stiffness matrices and load vectors are derived in general forms and a closed form can be easily obtained. The material is assumed to be isotropic and linear elastic. The presented procedure can be applied in analysis of marine, airplane, vessel structures etc. On the basis of the proposed procedure, a computer program has been developed. For justification of the proposed stress analysis as well as its accuracy, some examples are presented. Comparison with analytical and other numerical solutions is also provided.
