Sayadi, Sina (author), Chang, Z. (author), He, S. (author), Schlangen, E. (author), Mihai, I.C. (author), Jefferson, Anthony (author)This paper describes the development of a discrete lattice model for simulating structures formed from self-healing cementitious materials. In particular, a new approach is presented for simulating time dependent mechanical healing in lattice elements. The proposed formulation is designed to simulate the transient damage and healing behaviour...journal article 2023

Chang, Z. (author), Zhang, Hongzhi (author), Schlangen, E. (author), Šavija, B. (author)The lattice fracture model is a discrete model that can simulate the fracture process of cementitious materials. In this work, the Delft lattice fracture model is reviewed and utilized for fracture analysis. First, a systematic calibration procedure that relies on the combination of two uniaxial tensile tests is proposed to determine the input...journal article 2020
