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 کاملCreep Transition in a Thin Rotating Disc Having Variable Density with Inclusion
Creep stresses and strain rates have been obtained for a thin rotating disc having variable density with inclusion by using Seth’s transition theory. The density of the disc is assumed to vary radially, i.e. ( ) 0 / m r b ρ ρ − = ; 0 ρ and m being real positive constants. It has been observed that a disc, whose density increases radially, rotates at higher angular speed, thus decreasing the pos...
متن کاملElastic-Plastic Deformation of a Thin Rotating Disk of Exponentially Varying Thickness and Inclusion
Transition theory has been used to derive the elastic-plastic and transitional stresses. Results obtained have been discussed numerically and depicted graphically. It has been observed that for disc with exponentially varying thickness (k=2), high angular speed is required for initial yielding at internal surface as compared to the flat disc and exponentially varying thickness for k=4 onwards. ...
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 کاملElastic-Plastic Analysis for Finite Deformation of a Rotating Disk Having Variable Thickness with Inclusion
Transition theory has been used to derive the elasticplastic and transitional stresses. Results obtained have been discussed numerically and depicted graphically. It is observed that the rotating disk made of incompressible material with inclusion require higher angular speed to yield at the internal surface as compared to disk made of compressible material. It is seen that the radial and circu...
