The cylindrical tube having 4 layers of composites with a layup of optimum angles (i.e. α &β) is to be analysed in abaqus as per the
design for virtual reality testing. It is designed in such a way that it can the loading condition i.e. 1) an axial compression of 25 KN
& also have maximum angle of twist. The theory of laminate is employed in the design of the composite cylindrical tube to analyse
the stress & strains of the laminate in material principle direction & in laminate direction (structure direction). The maximum failure
criteria are used for safe design of the tube. The selection of winding angles play vital role in the design as it influences the
mechanical performance of the component. Numerical and analytical model of the composite tube are prepared. Numerical model of
the composite tube are prepared in Abaqus (FE analysis) software and compare with the analytical model. During the design the
Mathcad software is used to perform the mathematical calculation. We have used maximum stress failure criterion for the safe
design of the tube and Tsai-Wu Criterion is used for more accurate testing.
