A macrocrack in any solid under load gives a birth to microdefects in front of its tip. The scale level of the microdefects can be very different, from the atomic or dislocation level, in which case plasticity of some physical nature will occur, to the rather macroscopic level, microcracks and macrovoids being examples. The fracture toughness of the solid is determined by a complicated interaction of defects on different levels. It appears to be difficult to choose a predominant type of… CONTINUE READING
