Item THERMOELASTIC ANALYSIS OF HEAT GENERATING MULTI-LAYERED COMPOSITE CYLINDERS AND TUBES(2012-04-18) YILDIRIM, Murat; ARGEŞO, HakanA computational method is developed for the thermoelastic analysis of internally heat generating multi-layered composite cylinders and tubes having temperature dependent physical properties. The composite assembly is considered to be infinitely long and have axially constrained ends. In the formulations, small deformation theory is used. The layers that form the composite assembly are isotropic and have uniform heat generation. The thermal and mechanical problems are uncoupled and axisymmetric. The thermal problem is steady state and the mechanical problem is a plane strain problem. The computational model is based shooting algorithm. Both the thermal and mechanical problems are solved with the use of shooting algorithm. The computational model is first verified through the use of some benchmark problems that have analytical solutions in which the physical properties are considered to be temperature independent. The computational method is then used to solve some composite cylinder/tube assemblies that have temperature dependent physical properties.
