Over the past three decades, the double-K fracture model has received widespread
recognition and application in the field of engineering material fracture. As the …

The crack-tip fracture process zone (FPZ) length with distributed cohesive stresses is
commonly modelled for quasi-brittle fracture of heterogeneous solids. This study highlights …

To investigate fracture properties and find analytical solutions of fracture parameters at rock-
concrete interface, three-point bending tests were performed on the composite rock-concrete …

The aggregate particle gradation of concrete, which is generally characterized by a sieving
curve, is a critical factor affecting the formation of the core stress skeleton of concrete …

A new damage model is proposed in the bond-based peridynamics (BBPD) frame to
quantitatively investigate mode-I crack propagation in concrete, which is established based …

A crack propagation criterion for a rock–concrete interface is employed to investigate the
evolution of the fracture process zone (FPZ) in rock–concrete composite beams under three …

To investigate the interface mechanics and fracture properties and establish an interface
tension-softening constitutive law between concrete and rock for analyzing fracture failure of …

In this paper, an analytical method was introduced to investigate the size effect on the
unstable fracture toughness of fine-grained quartz-diorite. The analytical method can predict …

This study developed an integrated computational model to predict the time-dependent
elastic deformation behaviour of concrete materials under external sulfate attack. The …
