- W2068536435 abstract "Nowadays, an accurate determination of the true stress‐strain curve is a key‐element for all finite element (FE) forming predictions. Since the introduction of Advanced High Strength Steels (AHSS) for the automotive market, the standard uniaxial tension test suffers the drawback of relatively low uniform elongations. The extrapolation of the uniaxial stress‐strain curve up to large strains is not without consequence in forming predictions—especially formability and springback. One of the means to solve this problem is to use experimental tests where large plastic strain levels can be reached. The hydraulic bulge test is one of these tests. The effective plastic strain levels reached in the bulge test are of about 0.7. From an experimental standpoint, the biaxial flow stress is estimated using measurement of fluid pressure, and calculation of thickness and curvature at the pole, via appropriate measurements and assumptions. The biaxial stress at the pole is determined using the membrane equilibrium equation. The analysis proposed in this paper consists of performing “virtual experiments” where the results obtained by means of FE calculations are used as input data for determining the biaxial stress‐strain law in agreement with the experimental procedure. In this way, a critical discussion of the experimental procedure can be made, by comparing the “experimental” stress‐strain curve (Membrane theory curve) with the “reference” one introduced in the simulations. In particular, the influences of the “(die diameter)/thickness” ratio and of the plastic anisotropy are studied, and limitations of the hydraulic bulge test analysis are discussed." @default.
