Analysis and Performance of Adhesively Bonded Crush Tube Structures
(University of Waterloo, 2012-09-28)Lighter structural and energy absorbing materials are essential to increase fuel efficiency in transportation systems and have provided a motivation to investigate the use of new joining techniques based on the use of high ... -
Axial Crush Performance of Hot Stamped Tailor Welded Blanks - Experiments and Numerical Simulations
(University of Waterloo, 2019-01-30)This thesis investigates the axial crush performance of hot stamped tailor-welded blanks (TWBs) and their potential for weight reduction in the front crush structure of a vehicle. A baseline demonstrator structure, fabricated ... -
Characterization and Modelling of 3rd Generation Advanced High Strength Steel Automotive B-pillars from Forming to Crash
(University of Waterloo, 2022-09-26)This thesis investigates the application of 3rd Generation Advanced High-Strength Steels (3rd Gen AHSS) with ultimate tensile strengths of 980 and 1180 MPa to the forming and crash performance of an automotive B-pillar. ... -
Crashworthiness and Material Characterization of Multi-cellular AA6063 Extrusions
(University of Waterloo, 2017-05-17)This thesis investigates the crashworthiness characteristics of the AA6063-T6 aluminum extrusions with two different multi-cellular cross-sections. The profiles under study are referred to as the Omega cross-section which ... -
Dynamic and Quasi-Static Response of Warm and Hot Formed Aluminum Beams Under Three-Point Bending
(University of Waterloo, 2018-01-23)This thesis investigates the effect of elevated temperature forming on the impact resistance of three aluminum alloys, AA6013-T6, AA7075-T6, and a developmental 7000-series alloy (designated AA7xxx-T76). Both die quenching ... -
Experimental Testing and Modelling of Adhesively Joined T-structures
(University of Waterloo, 2015-10-02)As fuel-efficiency standards continue to push original equipment manufacturers (OEM's) to produce more fuel-efficient vehicles, it is important to look at new and innovative ways to achieve this goal. Although there are ... -
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, ...
