Limiting dome height data

NettetThe Limiting Dome Height (LDH) values are obtained by simulation and experimentation based on the hemispherical punch method. In simulation work, Barlat-89 yield criterion was used to obtain the Limiting Dome Height (LDH) values and strain distribution along with the specimen in Abaqus 6.1 software. NettetThe limiting dome height (LDH) test stretches a rectangular steel strip which is locked in the longitudinal direction (Figure 3). Typically, a conventional rust preventive oil coats …

Height of the cup, h at failure is used as formability index, higher this index is higher will be the formability of the material. The disadvantages of this test are first they cannot be correlated with other mechanical properties of the sheet metal and second these tests have poor data reproducibility. Limiting Dome Height Test (LDH) NettetThe process of the loss of stability is analysed for sheet metal subjected to biaxial tension when the ratio of the principal stresses 0.5 ⩽ σ 2 /σ 1 ⩽ 1. The loss of stability manifests itself by a groove running in a direction perpendicular to the larger principal stress. In this groove local strains begin to concentrate gradually. huda beauty sk
