Failure Characterization of Hot Formed Boron Steels with Tailored Mechanical Properties
(University of Waterloo, 2016-04-01)This thesis presents the results from characterization of the failure behaviour of hot stamped USIBOR® 1500-AS steel sheet with tailored properties. A phenomenological approach is used in which failure strain is characterized ... -
Investigation of effect of temperature and forming speed on the formability of AA3003 Brazing Sheets
(University of Waterloo, 2016-07-08)The present work investigates the effect of forming temperature and forming speed on the formability of AA3003 aluminum alloy brazing sheet in three temper conditions (O, H22 and H24) and two different thicknesses (0.2 and ... -
Investigation of Resistance Spot Weld Failure in Tailored Hot Stamped Assemblies
(University of Waterloo, 2018-01-23)This thesis presents the results from the mechanical characterization of resistance spot welds within hot stamped USIBOR® 1500-AS steel sheet (1.2 and 1.6 mm thickness) with tailored properties. Three parent metal conditions, ... -
A Methodology for Data-Informed Process Control in Progressive Die Sheet Metal Forming
(University of Waterloo, 2022-10-25)This thesis investigates the coupled relationship between the strip transfer and forming operations in progressive die sheet metal forming, including the effects of the strip layout geometry, and its effect on the process ... -
On the Development of Fold Initiator Patterns to Promote Progressive Folding of Hot Stamped Ultra-High Strength Axial Crush Structures
(University of Waterloo, 2021-06-21)The effect of fold initiator design on the performance of axial crush rails fabricated using ultra high strength steels (UHSS) is examined in a combined experimental-numerical-analytical study. Of particular interest is ... -
On the Response of 7000-Series Alloys to Hot Stamping
(University of Waterloo, 2020-01-07)Hot stamping, or die quenching (DQ), of 7000-series aluminum alloys is a metal forming process in which a blank is heated (solutionized) and then quenched and formed in cold tooling. The formed part is then subjected ... -
Refill Friction Stir Spot Welding Of Dissimilar Alloys
(University of Waterloo, 2015-12-22)Lightweight alloy materials such as magnesium and aluminum alloys are frequently employed in the automotive and manufacturing industry in order to improve vehicle fuel economy. This creates a pressing need for joining of ...
