Title Accounting the Influence of Cold Creep on Deformation of Structures

Abstract A computational-experimental method is proposed, which makes it possible to predict the creep process on a significant time basis (on the order of thousands of hours) on the basis of experimental data obtained on a significantly smaller time base. The study was conducted on titanium alloy at room temperature. It is shown that the obtained results expand the possibilities of using the existing methods for the calculation of structures with regard to creep.
