Strain localization analysis using a multiscale model [PDF]
, 2007 In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical constitutive law, which is then

Laser Welding of Coated Press-hardened Steel 22MnB5
Physics Procedia, 2017 Abstract The press-hardening process is widely used for steels that are used in the automotive industry. Using ultra-high-strength steels enables car manufacturers to build lighter, stronger, and safer vehicles at a reduced cost and generating lower CO 2 emissions.

Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts
Metals, 2018 Stamping dies perform two functions in the hot stamping process of body-in-white components. Firstly, they form the steel sheet into the desired shape and, secondly, they quench the steel at a cooling rate that leads to hardening by means of the ...

Strength determination for band-loaded thin cylinders [PDF]
, 2018 Cylindrical shells are often subjected to local inward loads normal to the shell that arise over restricted zones. A simple axisymmetric example is that of the ring-loaded cylinder, in which an inward line load around the circumference causes either ...

Journal of Materials Research and Technology, 2023 High-strength press-hardened steels (PHSs) are characterized by a martensite structure of high strength and adequate ductility. Strengthening PHSs with high C contents is usually accompanied by a loss of ductility and toughness. To overcome this inherent
