A specialised finite element for simulating self-healing quasi-brittle materials - data

The formation of cracks in quasi-brittle materials such as concrete produces a degradation in mechanical performance in terms of both stiffness and strength. In addition to this, the presence of cracks leads to significant durability problems, such as reinforcement corrosion and calcium leaching. Self-healing systems are designed to mitigate these issues by introducing crack ‘healing’ mechanisms into the material that result in a recovery of both mechanical performance and durability properties. This dataset contains the results produced by a new finite element that employs a strong discontinuity approach to represent discrete cracks and introduces healing variables at the element level, that is coupled with damage-healing model. The dataset comprises 3 Excel files, which correspond to, i) a convergence test concerning a singly notched prismatic specimen loaded in tension, ii) a direct tension test on a self-healing concrete with embedded channels and iii) loading of an L-shaped specimen with two hypothetical embedded channels.

Reserach results based upon these data are published at https://doi.org/10.1186/s40323-020-00171-4
