Elastic-Plastic Transition in a Thin Rotating Disc with Inclusion
Stresses for the elastic-plastic transition and fully plastic state have been derived for a thin rotating disc with inclusion and results have been discussed numerically and depicted graphically. It has been observed that the rotating disc with inclusion and made of compressible material requires lesser angular speed to yield at the internal surface whereas it requires higher percentage increas...
متن کاملModeling Anisotropy and Steady State Creep in a Rotating Disc of Al-SiCp having Varying Thickness
The analysis of steady state creep in a rotating disc made of Al-SiCp composite having variable thickness has been carried using Sherby’s constitutive model. The creep parameters have been evaluated using the available experimental results in the literature using regression analysis. Three variations in the thickness (constant, linearly and hyperbolic varying thickness) of the disc have been co...
متن کاملSteady Thermal Stresses in a Thin Rotating Disc of Finitesimal Deformation with Mechanical Load
Seth’s transition theory is applied to the problems of thickness variation parameter in a thin rotating disc by finite deformation. Neither the yield criterion nor the associated flow rule is assumed here. The results obtained here are applicable to compressible materials. If the additional condition of incompressibility is imposed, then the expression for stresses corresponds to those arising ...
متن کاملFrictional torque on a rotating disc
Resistance to motion often includes a dry frictional term independent of the speed of an object and a fluid drag term varying linearly with speed in the viscous limit. (At higher speeds, quadratic drag can also occur.) Here, measurements are performed for an aluminium disc mounted on bearings that is given an initial twist and allowed to spin until it comes to a stop. It is found that a sum of ...
متن کاملFGM ROTATING DISC FABRICATE BY Al/Al2O3
Our aim of is to develop a processing method for a rotating disc made of functionally graded materials (FGM), by stacking the slurry, layer by layer in a radial direction. A three-layer functionally graded material of Al/Al2O3 is fabricated with compositions of 10, 20, 30 vol.% Al2O3. The ceramic composition increases from the discs inner (centre) to the outer. The combination of these material...
