A safety factor of 3 was used on top of the stress intensity factor to determine minimum fracture toughness
Resilience, mental toughness
, "grit" is a quality worth striving *for and celebrating, even as we at times fall short.
by sportsmen and coaches, to achieve excellent performanceis considered to be one of the important psychological features (Bull, et al.
Our main experiment examined the effect of adhesive through-reinforcement (two levels) and the effect of glass-fibre reinforcement of adhesive bond lines on different measures of fracture toughness
of a model laminated birch wood composite (Figure 1).
The Sport Mental Toughness
Questionnaire (SMTQ) was used to measure mental toughness
In view of the above considerations, the present study a) verified whether mental toughness
discriminates winner and loser in a kickboxing competition and b) examined the relationship between mental toughness
and muscular power performance.
testing involved loading a bar of metal, containing a notch that has been sharpened by growing a fatigue crack to the required depth, until the point of failure.
The present research proposed that mental toughness
would be positively associated to behavioral activation system, which in turn may lead to improved mental health whereas it would be negatively related to behavioral inhibition system and fight-flight-freeze system.
From the literature review it concludes that Ball Indentation test provides methodology for calculation of plane strain facture toughness
which is essentially meant for conservative design of thick components.
The simulated samples were used for testing of hardness and impact toughness
; while they actually represent the weakest zone of welded joint within heat-affected zone (HAZ).
where [[sigma].sub.t] and [K.sub.IC] are the tensile strength and Mode I fracture toughness
of rock, respectively, with a coefficient of determination [r.sup.2] = 0.62.
From the fracture toughness
analysis of injection and compression mold grade PP, it was found that the toughness
is related to the initial notch depth, sample dimensions, temperature, and deformation rate ,The application of linear elastic fracture mechanics (LEFM) to measure the fracture toughness
of PP homopolymer is restricted to -60[degrees]C  because of the excessive nonlinearity at higher temperatures [13-15].
