Stress-stain state of pipe made of copper-based alloy strengthened with incoherent nanoparticles O. V. Matvienko, O. I. Daneyko, T. A. Kovalevskaya

P. 562-569Abstract: The approach which combines methods of crystal plasticity and deformable solid mechanics is used to explore the stress-strain state of a heavy-wall pipe made of dispersion-hardened Cu-based alloy and subjected to the uniform internal pressure. The distribution of the deformation and stress along the pipe wall is determined for various pipe geometry. The approximating equations are obtained to determine the yielding area and elastic and plastic strength limits.
