Based upon the concept of microcrack precursor nucleation, a microm¢chanics model is proposed to study the formation of near-tip microcracking and consequent toughening effects. Analytical expressions are derived for the microcrack density distribution and the size and shape of the microcracking zon
Based on the analysis of a representative elliptic microcrack embedded in a RVE, the additional compliance tensor induced by an embedded opening/closed microcrack is derived, and that corresponding to the kinked growth of a closed elliptic microcrack is also derived by making use of its approximatel
