The lattice model is a discrete model that is typically used to simulate the fracture process of
brittle materials. This review summarizes the main achievements during the development …

The dynamic impact damage of concrete will lead to serious safety accidents, and the water
environment will aggravate the degree of damage. In this paper, an infrared monitoring …

Considering that many numerical methods have been developed to study the mechanical
properties of rocks based on micro heterogeneities such as mineral size, morphology …

In the present work, a phase-field lattice model (PFLM) is proposed to model fracture
problems. The element deletion process and oversimplified failure criterion of the classical …

The interface transition zone (ITZ) is the weakest area in the concrete three-phase medium,
which directly affects concrete strength, stiffness, and durability. Because the ITZ has small …

This work presents an introduction to popular damage and fracture models along with the
major breakthroughs and the current state of the art. The theoretical and computational …

This article investigates the relationship between stress, damage, crack propagation, and air
(gas) permeability evolution in concrete using the Brazilian tension test. This investigation is …

The mixed mode I-II crack propagation process in concrete subjected to quasi-static
conditions has been extensively investigated. However, in engineering practice, many …

Unloading can cause many geotechnical disasters, eg, the rock burst. The underlying
mechanism of rock failure is the propagation and coalescence of cracks. To get insight into …

The mechanical properties and failure modes of concrete are affected by strain rate.
Therefore, various experimental methods have been used to quantify the strain-rate …
