Schmale, D T; Bourcier, R J

A biaxial deformation test system has been developed to perform tensile-compressive axial loading and internal-external pressurization of thin-walled metal tubes. The system has been added to an existing MTS 490 kN load frame with a PDP 11/34 based computer control system. It consists of: (a) specimen grips, (b) high pressure chamber, (c) a hydraulic intensifier and controller and (d) associated valving and switching. Software has been written in the MTS MultiUser-BASIC language to perform simple multiaxial cyclic deformation of a tubular specimen. The design of the mechanical test system and software are described and preliminary test results for the deformation of 316 stainless steel tubing under various proportional loading paths are presented. 19 refs., 14 figs.
