Experimental and numerical study of crack behaviour for capsule-based self-healing cementitious materials
HighlightsCrack behavior of capsule-based self-healing cementitious material was studied.A 2D lattice model was used to simulate the crack process.A real phase-segmented 3D structure was constructed based on 2D XCT images.Fracture behavior was compared between real structure and 3D lattice model.
AbstractA 2D lattice model was constructed to simulate crack process of in shell-interlayer-cement paste zone. The simulated tensile strength was validated by an experimental uniaxial tensile test and used as the input for a 3D lattice model, which was constructed to perform mechanical analysis based on a series of 2D X-ray microtomography images. The fracture behaviour of the 3D lattice model with assigned mechanical properties gave a similar crack pattern and tensile strength as the real structure. This study is expected to provide a feasible approach for investigating the fracture and trigger behaviour miccrocapsules embedded in a self-healing cementitious system.
