Mental toughness and overtraining behaviours
The idea of mental toughness (MT) is bewitching. The construct is consistently associated with success and being able to overcome great difficulties while demonstrating dogged perseverance regardless of adversity (Gucciardi, Gordon, & Dimmock, 2008; Jones, Hanton, & Connaughton, 2002). It is no …

Rheometric measurement of hydrogel toughness
… in measuring mechanical properties such as toughness. However, traditional tensile testing methods do not work for such materials due to the intrinsic softness of the material. We present a novel method for measuring fracture energy using a rheometer and show it is broadly consistent with …

Development of the Mental Toughness Situational Judgment Test: A Novel Approach to Assessing Mental Toughness
Mental toughness (MT) has been shown to predict outcomes across a variety of high-stress contexts such as athletics, the military, and the workplace. Despite this, researchers have struggled to reach consensus regarding how best to conceptualize and measure MT. Specifically, MT assessments have …

Mental toughness in elite football officiating
… an in-depth study into understanding Mental Toughness (MT) and its development within elite football referees. A secondary purpose was to use the findings of the series of studies contained herein, to bridge the gap between theory and applied practice by providing recommendations for football …

The Fracture Toughness of Fibre Concretes
… triangular elements.<br/><br/>Three new fracture toughness tests are proposed. Two of these tests are based on the traditional standard concrete quality control specimens. The tests are relatively easy to apply requiring a minimum of specimen preparation.<br/><br/>The fracture toughness values …

The impact toughness of iron manganese alloys.
… The present investigation shows that impact toughness can be improved by tempering to produce small amounts of reverted austenite into the structure. In quantifying the percentages of reverted austenite in these structures. X-ray and Mossbauer studies have shown that the phase analysis of …

Bone fracture toughness of estrogen deficient rabbits
… and estrogen deficiency, using fracture toughness, femoral neck fracture and histomorphometric analysis in an ovarectomized rabbit model.;No significant differences were found in fracture toughness, porosity, or femoral neck ultimate strength for any treatment group, which may have be …

Design of Welding Alloys Creep and Toughness
The subject of welding is challenging because of its complexity and because its applications are in the majority of cases, safety critical. The work presented in this thesis deals with both these aspects from the point of view of welding alloys. (part)

Mental Toughness in the Classical Martial Arts
The construct of mental toughness is in a state of evolution and refinement. The current study proposed to investigate; (1) the importance of mental toughness attributes from a Classical Martial Arts context, (2) the trainability of the mental toughness attributes from a Classical Martial Arts …

The fracture toughness of ultrafine WC-Co Alloys
This thesis examines the fracture toughness behaviour of a series of cemented carbides having carbide grain sizes between 0.35f.Lm and 4f.Lm, cobalt contents ranging from 6 to 15wt%, and vanadium carbide contents from 0 to 0.8wt%. A series of twenty-four ultrafine WC-Co alloys were sintered from …

Rheological measures of the fracture toughness of hydrogels
… a method is proposed to determine the fracture toughness of a notched hydrogel using rheology, as opposed to tensile tests. Notched polyacrylamide hydrogels underwent constant strain rate tests on a rheometer to fracture the samples. Tensile tests were performed on notched samples as a baseline …

High fracture toughness and high modules silicone resins
… modulus and other properties. High fracture toughness and modulus addition cure rigid silicone resins are obtained in this study by a combination of intrinsic toughening and extrinsic toughening techniques. The addition cure silicone resin comprises two components: polyphenylsilsesquioxane …

Transformation and toughness of iron-9 percent nickel alloy.
Phase transformation studies have been carried out on VS2241A, Fe-9.14Ni -0.002C alloy. This alloy was chosen because it was expected that the speed of austenite decomposition would be slow enough to allow continuous cooling transformation and isothermal transformation experiments to be carried out …

Mental toughness, servant leadership, and the collegiate distance runner
<p>"Mental toughness is commonly associated with successful performance in the realm of athletics. However, despite the prevalence of its usage, the concept remains somewhat ambiguous in its definition and practical application. The purpose of this study was to determine the relationship between …
