Abstract:

This investigation deals with the development and application of a simple testing technique which measures the strength of metallic sheets and weldments under biaxial loading conditions, simulating those found in a cylindrical pressure vessel. The test technique employed is a simply slotted sheet tensile specimen, which uses a large elastic bulk to restrain plastic flow in a direction perpendicular to that of the applied tensile load, thus creating a condition of plane strain. The following conclusions may be drawn 1 A slotted sheet specimen may be used to create a condition of plane tensile strain and associated two-to-one bi-axial tensile loading in weldments and base metals. 2 The specimen offers the simplest method yet developed to measure the effects of bi-axial loading upon tensile strength. 3 Under conditions of two-to-one tensile loading, the strength of heat-treated alloy steel sheet and weldments is raised appreciably. 4 Tensile strength increases of greater than 10 are possible for both base metals and weldments, but the magnitude of this increase may be influenced by both strength level and weld quality.
