Understanding the inconsistent rock fracture toughness (K Ic) measurement results from
different test specimen geometries helps provide suitable fracture parameters for …

Damage tolerance design approach such as the fatigue crack propagation approach
provides a more realistic solution for fatigue problems in concrete to overcome the …

The aggregate size plays an important role in the nonlinear mechanical behaviour of
concrete, which is strongly related to the size effect. In this study, the meso-mechanical …

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 …

Tensile fractures in deep coal and rock mass can readily trigger dynamic calamities like rock
bursts, significantly impacting the safety of coal mining. To enhance our understanding of …

Evaluating the fracture resistance of rocks is essential for predicting and preventing
catastrophic failure of cracked structures in rock engineering. This investigation developed a …

Hoover, Bazant and colleagues have published a number of papers in recent years (Bazant
and Yu, 2009; Yu, 2010; Hoover and Bazant, 2013a, 2013b, 2014) on comparisons between …

This paper aims to investigate the fracture properties and microscopic mechanisms of multi-
scale nano-SiO 2 (NS) and polyvinyl alcohol (PVA) fiber-reinforced cementitious composites …

The effects of specimen geometry on mode I and mode II fracture toughness (ie, K Ic and K
IIc), and the ratio of K IIc to K Ic for a given rock material were derived on the basis of a …

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 …
