Change the transverse deformation of viscoplastic

Metallurgy and materials technology. Mechanical engineering

The results of experimental studies of the transverse deformation caused viscoplastic material properties. The experiments were conducted at ambient temperature over a thin-walled tubular specimens of stainless steel in the face of increasing and constant load. Found that the coefficient determined by the results of instantaneous and quasi-static loading, and relative components of viscoplastic strains are kept secure and do not differ on the whole interval of homogeneous elastic deformation. The coefficients established by experiments on creep under constant load, depending on the load at which the experiment was.
