Fatigue Characterization of Asphalt Mixes with Polymer Modified Asphalt Cement
(University of Waterloo, 2018-11-14)Asphalt pavement cracking is the most prevalent distress in pavements. In flexible pavements, fatigue cracking is a major cause of deterioration and can significantly reduce the service life of pavements [1]. Fatigue ... -
Fatigue Design and Behaviour of Carburized Steel
(University of Waterloo, 2022-05-02)Steel is an essential component used in infrastructure, automobiles, machines and many other areas due to its low cost and high tensile strength. Carburization is a heat treatment process commonly used to harden and ... -
Fatigue Flexural Behaviour of Reinforced Concrete Beams with Non-Prestressed and Prestressed Basalt Fiber Reinforced Polymer Bars
(University of Waterloo, 2015-06-18)Basalt fibers have recently been introduced as a promising alternative to the existing fiber reinforced polymer (FRP) family. The mechanical properties of basalt FRP (BFRP) bars are, generally, better than those of glass ... -
Fatigue Life Assessment of 30CrNiMo8HH Steel Under Variable Amplitude Loading
(University of Waterloo, 2013-01-18)The actual service loading histories of most engineering components are characterized by variable amplitudes and are sometimes rather complicated. The goal of this study was to estimate the fatigue life of nickel-chromiu ... -
Fatigue Life Prediction Based on the Advanced Fatigue Crack Growth Model and the Monte-Carlo Simulation Method
(University of Waterloo, 2015-01-05)It is well-known that loss of the structural stability due to propagation of the dominant crack is one of the main sources of fatigue failures. Therefore, computationally feasible fatigue crack growth model is essential ... -
Fatigue Life Prediction of an Automotive Chassis System with Combined Hardening Material Model
(Society of Automotive Engineers, 2016-04-05)The choice of an appropriate material model with parameters derived from testing and proper modeling of stress-strain response during cyclic loading are the critical steps for accurate fatigue-life prediction of complex ... -
Fatigue of Aluminum Welds in Canadian Highway Bridges
(University of Waterloo, 2010-08-30)Aluminum is the most common metal in the world and its high strength to weight ratio, along with excellent corrosion resistance, can provide efficient solutions for the design and rehabilitation of highway bridge structures. ... -
Fatigue of Forged AZ80 Magnesium Alloy
(University of Waterloo, 2019-09-25)The majority of research surrounding the fatigue of Mg alloys generally exhibits a rigid dichotomy between theoretical and applied contributions. This research work addresses both of these domains of the field from a more ... -
Fatigue related impairments in oculomotor control are prevented by caffeine
(Nature, 2016-05-25)Strenuous exercise can result in an inability of the central nervous system to drive skeletal muscle effectively, a phenomenon known as central fatigue. The impact of central fatigue on the oculomotor system is currently ... -
The Fatigue Resistance of Headed Shear Stud Connectors in Steel-Precast Composite Girders
(University of Waterloo, 2017-01-20)Extensive research dating back to 1965 has been conducted on the fatigue performance of headed shear stud connectors in steel and cast-in-place composite girders. However, little research has been conducted specifically ... -
Fatigue Testing and Analysis of Aluminum and Steel Partial Joint Penetration (PJP) Welds for Bridge Applications
(University of Waterloo, 2023-05-30)Partial joint penetration (PJP) welds are a cost-effective alternative to full penetration welds and have certain advantages, especially in situations where a full penetration weld is unnecessary and the stress on the weld ... -
