formability testing of sheet metals - Sphinxworldbiz

Posted by Anii Jain on October 22nd, 2019

The multi-point forming (MPF) process of spherical surface parts of titanium alloy retiary sheet and titanium alloy sheet metal with different thickness and curvature radius was simulated by an explicit finite element software. Contradistinctive analysis between the retiary sheet and sheet metal forming parts with different modes were done. The simulation results show that under the same forming conditions, titanium alloy retiary sheet is not easy to wrinkle and spring back, whereas it is easy to form. The reason for differences in the formability sheet metal is also analyzed. A non-wrinkling limited graph and a fracture critical graph for spherical surface parts of retiary metal sheet and metal sheet were obtained. Finally, a forming test of titanium alloy cranial prosthesis was done in MPF press. Testing results indicate the customized 3D curved surface of a prosthesis can be adequately shaped and the forming quality was guaranteed.

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.

  • At Sphinx, we confirm the process model against failure by giving the following outputs:
  • 3D CAD surface model of the drawn panel with addendum & binder surface
  • Blank size and shape optimization
  • Cost-effective material grade selection for successful formability
  • Draw bead locations, strengths and geometry
  • Press cushion loads and draw load estimation.
  • Movement of impact (shock) lines in visible panels
  • Sound domain knowledge of sheet metal
  • Part processing and tool design
  • Digital prototyping of tool design
  • Quality checks for surfacing
  • Formability analysis post-processing
  • Engineering interpretation of key result areas like
  • Thickness distribution, thickening, thinning /cracking
  • Waviness, wrinkles, folds
  • Stress levels for panels for dent resistance and taunt looks
  • Shock lines/skid lines
