An elasto-plastic analysis of compound cylinder was investigated in this thesis. Modified-shrink-fit (MSF) method of compound cylinder was utilized to increase the elastic load carrying capacity (ELCC) of cylinder. The autofrettage process of monobloc cylinder was extended to study the MSF process. Theoretical analyses were based on the Tresca yield criterion, Hencky's total strain theory, infinitesimal strain concept, $dε_z^p=0$ and equilibrium equation.
The specimens were made of full annealed low carbon steels, SM20C and SM45C. Residual stresses were measured by the Sachs boring-out method and the Babaev's solution for the monobloc and compound cylinder, respectively. The increase of ELCC of cylinder was obtained by the autofrettage and the MSF process. In a point of view of safety and economical efficiency, it was found that the Modified-shrinkfitted compound cylinder was better than the autofrettaged monobloc cylinder.
