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 …

Many modern engineering structures are composed of brittle heterogenous, or quasibrittle,
materials. These include concrete, composites, tough ceramics, rocks, cold asphalt mixtures …

Size effect experiments using geometrically similar specimens of different sizes overlap
boundary effect experiments using specimens of single size but different notches if sufficient …

This article discusses the scale dependence of the mode I fracture toughness of rocks
measured via the semi-circular bend (SCB) test. An extensive set of experiments is …

In this research, the fracture characteristics and size effect of ultra-high performance fiber
reinforced concrete (UHPFRC) are investigated by notched three-point bending beam test …

The fracture properties of concrete subjected to drying-wetting cycles in different types of
sulfate solutions were investigated. Five exposure conditions, ie 5% and 10% sodium sulfate …

Purpose of this research is to apply the Bažant's size effect law to investigate the effects of
material properties, specimen size, normalized crack length and loading span on the …

Understanding the size effect of UHPC under compression is fundamental and essential for
component and/or structure design and analysis. This paper investigated the size effect of …

Quasi-brittle fracture properties of a medium-grain sandstone with an average grain size G
around 0.3–0.4 mm were investigated under three-point-bending (3-pb) conditions. In total …

Material heterogeneity strongly influences the fracture process zone in concrete, which is
responsible for the exhibition of size effect in the nominal strength. The fundamental aspect …
