Evaluation on water bursting risk of working faces near collapse column during the mining process [PDF]

E3S Web of Conferences, 2020
Collapse column water bursting occurs from time to time in the coal mining process of North China Type Coalfield in China, which causes great economic loss and personal injury. Therefore, great attention must be paid to the harm of collapse column.

Influence of surface tension in the surfactant-driven fracture of closely-packed particulate monolayers [PDF]

, 2017
A phase-field model is used to capture the surfactant-driven formation of fracture patterns in particulate monolayers. The model is intended for the regime of closely-packed systems in which the mechanical response of the monolayer can be approximated as

A New Model for Void Coalescence by Internal Necking [PDF]

, 2010
A micromechanical model for predicting the strain increment required to bring a damaged material element from the onset of void coalescence up to final fracture is developed based on simple kinematics arguments.

Mathematical Modeling of Hydraulic Fracture Formation and Cleaning Processes

Energies, 2022
The effectiveness of the hydraulic fracturing procedure is crucially dependent on the stage of fracture planning and design. Forecasting fracture behavior in rock formations characterized by non-uniform toughness is a serious challenge.

Interpreting experimental fracture toughness results of quasi-brittle natural materials through multi-parameter approaches

Fracture and Structural Integrity, 2015
Natural stones like marbles are often employed as façade panels to externally cover buildings. These natural materials tend to exhibit a quasi-brittle nonlinear fracture behaviour which, conversely to concrete counterpart, has much less been studied in ...

Cohesive Dynamics and Brittle Fracture

, 2015
We formulate a nonlocal cohesive model for calculating the deformation state inside a cracking body. In this model a more complete set of physical properties including elastic and softening behavior are assigned to each point in the medium.

Influence of Microscopic Effects on the Static Tensile Strength of Gray Cast Iron HT200 Specimens

Advances in Materials Science and Engineering, 2021
Gray cast iron HT200 material is a kind of pearlitic gray cast iron. Flake graphite in the gray cast iron greatly destroys the integrity of the matrix and affect the static strength.

Modeling with structure of resins in electonic compornents [PDF]

, 2006
In recent years, interfacial fracture becomes one of the most important problems in the assessment of reliability of electronics packaging. Especially, underfill resin is used with solder joints in flip chip packaging for preventing the thermal fatigue ...

A simulation method for fatigue-driven delamination in layered structures involving non-negligible fracture process zones and arbitrarily shaped crack fronts

, 2019
Most of the existing methods for fatigue-driven delamination are limited to two-dimensional (2D) applications or their predictive capabilities have not been validated in three-dimensional (3D) problems.
