DISPLACEMENT CALCULATION METHOD OF 0° AND 90° WINDING ANGLE CIRCULAR AND NON-CIRCULAR CROSS-SECTION BEAM UNDER TENSILE AND BENDING LOADINGS

Abstract

Abstract:

The work here presents a calculation method for displacements of 0°and 90°winding angle circular and non-circular cross-section beam under tensile and bending loadings.The method involves dividing the beam into finite beam elements,analyzing the elements displacements,strains and stresses of beam elements,transforming the coordinates,integrating displacements and loads of beam elements on the beam and obtaining the displacements of beam under tensile and bending loadings.Comparison between theoretical results and numerical results are done and they have a good agreetment.The results show that the presented method can be used for calculating the displacments of 0°and 90°winding angle circular and non-circular cross-section beam under tensile and bending loadings.

Key words: filament winding, composite, circular and non-circular cross-section beam, tensile and bending loadings, displacement
