Abstract: Understanding the crack and capsule interaction is critical in the development and design of structures made of autonomous self-healing materials. Continuing our previous study, in this contribution a more practical rupturing mode of capsules characterizing the rupturing manner of capsules fractured by cracks is presented in cementitious material, i.e., penetrating mode. With the underlying assumption that a crack penetrating capsules leads to crack healing, a probabilistic method is employed to develop the analytical expression between crack size and capsule size, capsule concentration. The influences of the rupturing modes of capsules embedded on the self-healing efficiency are also analyzed. Attention will be paid to compare the penetrating probability and the hitting probability, in order to assist the designer to choose the optimal rupturing modes of capsules embedded in cementitous materials.
