Strain Distribution Analyses of Sheared AHSS
Abstract Manufactured goods subjected to complex forming operations, such as drawing, piercing, or stamping, involve cutting and shearing into blanks; shearing promotes the development of strain gradients within the piece, which may result in cracks or fissures in the finished component, and would cause the rejection of the blank.

FLSD as a good choice in sheet forming of AHSS
, 2011 The automotive industry has increased significantly the use of advanced high strength steels (AHSS) in many structural components, with the aim to reduce weight and also to increase safety. The high resistance of these steels is accompanied by a decrease in formability, which makes simulation a requirement to adequately foresee the ...
