Elastic-plastic transition stresses in rotating cylinder by finite deformation under steady state temperature


The problem of elastic-plastic transition stresses of thick walled rotating cylinder by finitesimal deformation under steady state temperature has been solved by using the concept of generalised strain measure. It has been seen that with the increase of temperature, the cylinder having smaller radii ratios requires lesser angular velocity to become fully plastic as compared to cylinder having higher radii ratios. The result for the combined effect of rotation and temperature are calculated for fully plastic and depicted graphically.
