Unsteady thermal stress of thick-walled cylinder in the case of rapid cooling of the bore was analyzed by two methods; the elastoplastic stress analyzed by successive approximation proposed by S. S. Manson, and the viscoelastic stress according to the associate elastic problem, applying the analogy between the elastic and the viscoelastic solution.
Numerical calculation was also made of the stress for the cylinders of several dimensions.
The theoretical stress distribution was compared with the experimentally decided stress distribution based on the residual stress, and it was found that there was very good agreement between them.
