Stress fracture definition: a hairline crack in a bone, especially of a foot or leg, caused by repeated or prolonged stress and often occurring in runners, dancers, and soldiers (march fracture ). See examples of STRESS FRACTURE used in a sentence.
Toughness and brittleness are two concepts that are completely opposite to each other in terms of meaning. The higher a material’s toughness is, the lower its brittleness will be, and vice versa. Toughness is measured by two indices: impact toughness and fracture toughness. Impact toughness ...
Within the nonmilitary population, stress fractures tend to occur more frequently in patients who are active[1,2]. The term “active patient” has a different meaning for each individual patient. For example, a young 20-year-old patient may have to run or jog 3 to 5 days per week to ...

The meaning of study on single particle crushing is recognized at which it is regarded the accumulation of single particle crushing as the comminution performed in practical operations stochastic phenomena. Especially, experimental data concerning the mechanical properties of brittle solids measured under dy...
where the meaning in the Eq. (1) is shown in Fig. 1. The expression of stress in surrounding rock of borehole wall can be written as: $$ \sigma_{\rho } = - \frac{{\frac{{R_{2}^{2} }}{{r^{2} }} - 1}}{{\frac{{R_{2}^{2} }}{{R_{1}^{2} }} - 1}}p,\...
Fracture Mechanicsis a graduate level text/professional reference that describes the analytical methods used to derive stress and strain functions related to fracture mechanics. The focus of the book will be on modeling and problem solving as tools to be used in interpreting the meaning of a mathem...
