Creep transition of a transversely isotropic disc having variable thickness under internal pressure
Answers
Answer:
Elastic-plastic stresses have been derived for transversely isotropic disc having variable thickness under internal pressure using Seth's transition theory.
Explanation:
Creep stresses and strain rate have been obtained for an isotropic disc having variable thickness subjected to internal pressure. Results have been discussed numerically and depicted graphically. It has been observed that circumferential stress has maximum value at the internal surface for a flat disc and at external sufrace for a disc having variable thickness. This value of circumferential stress further increases with the increase in measure. Strain rates have maximum values at the internal surface for flat disc made of incompressible material whereas reverse is the case for the disc having variable thickness. These values of strain rates further increase with the increase in pressure and measure for a disc made of incompressible material.
