In vehicle crash events there is the potential for fracture to occur at the processed edges of structural components. The ability to avoid these types of fractures is desired in order to minimize intrusion and optimize energy absorption. However, the prediction of edge cracking is complicated by the fact that conventional tensile testing can provide insufficient data in regards to the local fracture behavior of advanced high strength steels. Fracture prediction is also made difficult because… 
Micromechanical modelling of edge failure in 800 MPa advanced high strength steels
Abstract Sheared edge failure is one of the major problems associated with the forming of advanced high strength steels (AHSS) such as dual-phase (DP) steels. To improve the performance of AHSS in
Evaluation of edge formability in high strength sheets through a fracture mechanics approach
Edge fracture prediction in high strength cold formed components still being a challenge for automotive part manufacturers. Even though several experimental methodologies have been proposed in the
Prediction of edge fracture during hole-flanging of advanced high-strength steel considering blanking pre-damage
Abstract The stretch-flangeability of advanced high-strength steel (AHSS) sheets after blanking highly depends on the stress states as well as the edge pre-damage inherited from the initial blanking
Experiments and FE simulation of edge cracking considering prehardening after blanking process
Edge cracking is a significant problem in the stamping of advanced high-strength steels (AHSS) and is very sensitive to the local material properties at the sheared edge after the blanking process.
Determining the influence of shear cutting parameters on the edge cracking susceptibility of high-strength-steels using the edge-fracture-tensile-test
Abstract The usage of high-strength-steels allows for the reduction of a component's weight by reducing the sheet thickness. During the production process of such components, shear cutting is
FE simulation of edge fracture considering pre-damage from blanking process
Abstract Edge fracture has been a well-known challenge in the forming processes of Advanced High Strength Steels (AHSS). The difficulty of the problem mainly lies in the complex loading path of
Assessment of the Critical Parameters Influencing the Edge Stretchability of Advanced High-Strength Steel Sheet
The edge formability of ferritic-martensitic DP (dual-phase) and ferritic-bainitic CP (complex-phase) steels was evaluated using a hole expansion test for different edge conditions. Hole expansion
Damage Evolution in Complex-Phase and Dual-Phase Steels during Edge Stretching
TLDR
The CP microstructures were shown to be less prone to shear-induced damage than the DP materials resulting in much higher sheared edge formability and an analytical model for void evolution and coalescence was developed and applied.
Reduction of cross section area at fracture in tensile test: measurement and applications for flat sheet steels
This contribution deals with the use of maximum thinning and reduction of sample cross section area at fracture after tensile testing and applications for industrial flat sheet steels. Although
Characterization of Sheared Edges in Warm Blanking of Magnesium Alloy AZ31B
TLDR
It was concluded that the blanking of magnesium alloy sheets at room temperature results in sheared edge defects, due to premature fracture, referred to here as micro-cracks, loose particles, and a jagged-plus-curved fracture profile, however, such deformities were completely suppressed with the rise in temperature.
