Equipment for Testing Sheet Structural Materials under Biaxial Tension. Part 1. Testing under One-Sided Pressure of the Working Medium

We consider specific features of the design of equipment for the investigation of strength and regularities of fracture of sheet structural materials under biaxial tension created by loading specimens by one-sided pressure of the working medium. We propose solutions of several methodical problems connected with testing under high pressures of the working medium which enable one to realize the required modes of cooling of the specimens, decrease the level of fracture energy, and increase the reliability and safety of testing.
