Scale-Size and Structural Effects of Rock Materials / Коэффициент масштабирования и структурный эффект в горных породах

In general, the term “size effect” refers to the influence of sample size on mechanical characteristics such as strength. Size effects in rock engineering have been of particular interest over the last four decades and many studies have been undertaken to understand the phenomenon. Size effects are not limited to rock. Almost all quasibrittle and brittle materials such as concrete, ceramic, and ice have shown some form of size effect.
