The effect of sample size is a phenomenon that involves the dependence of resistance on the size of the tested sample, where smaller samples exhibit higher resistance compared to larger ones. Due to the importance and sensitivity of determining the resistances of laboratory samples for use in design, codes, and standards, efforts are made to minimize the effects of sample size. This issue holds [...]

Mechanical yield strength is one of the most crucial mechanical properties to consider to remain operating in safe elastic regimes. Despite its importance, it remains ambiguous to measure as different disciplines acknowledge different definitions. Most common examples include the deviation from linear elasticity or the peak stress. This difference has significant consequences for the modelling of [...]
