Prediction on Crack Propagation of Concrete due to Time-Dependent Creep under High Sustained Loading

Jie Li et al.

Summary: This study investigated the effects of sustained loading on crack propagation in concrete. Experimental tests and numerical simulations were conducted to determine the crack growth behavior. The results showed that under high sustained loading, the crack growth rate initially decreased and then increased, with an inflection point characterizing the stability of the concrete structure.

Investigations on fracture properties and analytical solutions of fracture parameters at rock-concrete interface

Wenyan Yuan et al.

Summary: The study found that the roughness degree of the rock-concrete interface significantly affects its fracture properties. As the roughness degree increases, the fracture energy, critical crack length, and double-K fracture parameters show obvious increasing tendencies, while the ratio of the unstable fracture toughness of the rock-concrete interface to concrete is much less than that of the initial fracture toughness, indicating a weaker cohesive effect compared with concrete.
