Dear all,
Our group at TU Delft has recently published two articles dealing with use of numerical fracture models for design of capsule carriers for their use in self healing concrete.
For design of tubular capsules: https://www.researchgate.net/publication/311861983_Simulation-Aided_Desโฆ
For design of spherical capsules: https://www.researchgate.net/publication/319542777_Experimental_and_numโฆ
Hope you will find the articles interesting.
Regards
