Formability of Aluminium - Sphinxworldbiz

In the present work, formability of five sheets of aluminium-killed extra-deep drawing (EDD) low carbon steel sheets (with a wide variation in thickness) has been characterized. Forming limit diagrams (FLDs) have been determined experimentally by conducting punch-stretching experiments using suitably designed and fabricated tools. Formability, observed from FLDs, has been correlated with microstructure, mechanical properties and formability parameters like strain hardening coefficient (n) and normal anisotropy. We, as a referred name for Formability Analysis, have simulated many components of Indian & overseas customers. Our high degree of correlation with shop floor try-outs has been an added advantage for clients. From feasibility to production there are many kinds of simulations studies that are undertaken by our expert team of analysts.The strain distribution in the material during punch-stretching under different states of strain has been studied. From the experimental results, it has been found that four of the five sheets have a favourable grain size and mechanical properties to meet the requirements of good formability. The suitability of these sheets for critical deep-drawing applications has been examined in terms of the level and range of critical strains in the FLD. These results correlated well with formability parameters. Earing tendency during drawing is expected to be high for one sheet due to its high planar anisotropy. The level of the FLD increased significantly with the sheet thickness. The effect of n and on the strain distribution characteristics has been analyzed.
