Springback is a serious problem in sheet metal stamping. It measures the difference
between the final shape of the part and the shape of the forming die. Sheet metal forming …

Spring-back is a very common and critical phenomenon in sheet metal forming operations,
which is caused by the elastic redistribution of the internal stresses after the removal of …

The quality of springback prediction for a sheet metal forming process depends on a precise
estimate of the elasto-plastic stress distribution throughout the metal sheet. The use of low …
