This paper develops a model that only requires two sets of small-size rock specimens with
the ratio of the structural geometry parameter maximum to minimum ae, max: ae, min≥ 3: 1 …

Static fracture testing was performed on ISRM-suggested semi-circular bend (SCB)
specimens with a constant CMOD increment rate of 0.0002 mm· s− 1, and the digital image …

The stress intensity factor (SIF) is not only an important parameter in the field of fracture
mechanics but also a key indicator reflecting the strength of the stress field at the crack tip …

Technical advances in additive manufacturing (AM), also known as three-dimensional (3D)
printing, have led to applications of this technology in creation of end-use items …

In this paper, mode I fracture toughness of rock was determined by direct and indirect
methods using Particle Flow Code simulation. Direct methods are compaction tension (CT) …

It is well known that the measured values of the fracture toughness of rocks are influenced
by material heterogeneity, dimensions, boundary conditions, and asymmetric mechanical …

The importance of rate on the mechanical properties of rocks has been widely
acknowledged by numerous scholars. Currently, most researchers mainly focus on …

We introduce a simplified pseudo-compact tension (pCT) test apparatus, specifically
designed to accurately determine the mode I fracture toughness (K IC) under direct tension …

A new test configuration called Holed‐Cracked Square Plate (HCSP) is proposed to
investigate I/II mixed‐mode fracture of brittle and quasi‐brittle materials. This specimen is a …

Studies on the biaxial strength criterion provide a significant theoretical basis for the
exploration of concrete material's biaxial and multiaxial mechanical properties. In this study …
