Characterization and Modeling of Sheared Edge Failure in Advanced High Strength Steel
PATHAK, NIKKY (University of Waterloo, 2018-03-07)Edge failure is one of the major problems associated with forming of advanced high strength steels (AHSS) such as dual-phase (DP) steels. The development of ferritic-bainitic steels such as complex-phase (CP) steels have ... -
Damage Evolution in Complex-Phase and Dual-Phase Steels during Edge Stretching
PATHAK, NIKKY; Butcher, Clifford; Worswick, Michael J.; Bellhouse, Erika; Gao, Jeff (Multidisciplinary Digital Publishing Institute, 2017-03-27)The role of microstructural damage in controlling the edge stretchability of Complex-Phase (CP) and Dual-Phase (DP) steels was evaluated using hole tension experiments. The experiments considered a tensile specimen with a ... -
Failure parameter identification and validation for a dual-phase 780 steel sheet
Anderson, David; Butcher, Clifford; Pathak, Nikky; Worswick, Michael J. (Elsevier, 2017-10-01)A hybrid experimental-numerical procedure was implemented to determine the failure surface of a dual-phase 780 steel sheet as a function of the effective plastic strain, triaxiality, and Lode parameter using butterfly ...
