... analysis on a V-bending of the LSS over an 88 deg mold so as to obtain 90 deg V-shape products by offsetting the springback phenomenon. 1 Corresponding author. Contributed by the Manufacturing Engineering Division of ASME for publication in the J OURNAL OF M ANUFACTURING S CIENCE AND E...

... all reduce, the experimental results reduce from 5806 mm to 190 mm, the simulation results reduce from 5924 mm to 199 mm, and the simulation springback rates with filler reduce from 0.92% to 0.15%. It is proved that high geometric accuracy of the integral panels can be obtained by using filling roll...

...P.-A. Eggertsen; K. Mattiasson; J. Hertzman The springback phenomenon is defined as elastic recovery of the stresses produced during the forming of a material. An accurate prediction of the springback puts high demands on the material modeling during the forming simulation, as well as during...

...Hyunok Kim; Ninad Nargundkar; Taylan Altan In the fabrication industry, one of the critical challenges is to maintain close geometric tolerances in finished products, particularly in the air bending process. In many cases, this problem is related to springback and plastic elongation/compression...
