Failure parameter identification and validation for a dual-phase 780 steel sheet
(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 ... -
Fracture Mechanisms in Resistance Spot Weld of Magnesium Alloys
(University of Waterloo, 2015-06-19)The automotive industry is adopting the application of magnesium and magnesium alloys in order to produce light-weight auto-body structures. Therefore, it is essential to evaluate the load bearing capability of these metals ... -
Investigation of Liquid-Metal-Embrittlement Crack-path: Role of Grain Boundaries and Responsible Mechanism
(University of Waterloo, 2020-07-24)Liquid metal embrittlement (LME) has been reported in many structural materials, including steel, aluminum, nickel during hot working processes e.g. welding, brazing, heattreatment, leading to abrupt failure. In many of ... -
Monotonic and cyclic behaviour of cast and cast-forged AZ80 Mg
(Elsevier, 2017-11)Tensile and strain-controlled fatigue tests were performed to investigate the influence of forging on the performance of cast AZ80 magnesium alloy. The obtained microstructural analysis showed that the as-cast AZ80 magnesium ... -
On the Influence of the Through-Thickness Strain Gradients for Characterization of Formability and Fracture of Sheet Metal Alloys
(University of Waterloo, 2019-01-25)The main focus of this thesis is to investigate the effect of through-thickness strain gradient on sheet metal formability. Current technology for formability analysis has relied upon deformation modes of in-plane stretching ...
