This document specifies a method for determination of the biaxial stress-strain curve of metallic sheets having a thickness below 3 mm in pure stretch forming without significant friction influence. In comparison with tensile test results, higher strain values can be achieved. NOTE In this document, the term "biaxial stress-strain curve" is used for simplification. In principle, in the test the "biaxial true stress-true strain curve" is determined.
Abstract
Overview
EN ISO 16808:2022 - Metallic materials - Sheet and strip - Determination of biaxial stress-strain curve by means of bulge test with optical measuring systems specifies a standardized bulge (hydraulic) test method to determine the biaxial true stress–true strain curve of metallic sheets and strips with thickness below 3 mm. The method records deformation while a circular blank is clamped and pressurized with fluid until fracture. Compared with tensile testing, the bulge test can reach significantly higher strain values, providing data for biaxial forming conditions.
