Hydraulic fracturing is a stimulation technique that plays a critical role to provide transport path networks in unconventional shale reservoirs, yet the quantitative characterization of fracture propagation, its interaction with natural discontinuities, and the resulting stimulated volume remain challenging in heterogeneous formations such as the Vaca

Numerical modelling of intergranular fracture in polycrystalline materials and grain size effects
In this paper, the phenomenon of intergranular fracture in polycrystalline materials is investigated using a nonlinear fracture mechanics approach. The nonlocal cohesive zone model (CZM) for finite thickness interfaces recently proposed by the present ...

This study experimentally investigates the development and properties of sisal and jute woven mat epoxy composites that offer uniform fiber distribution and ease of fabrication, with the mat structure significantly enhancing wear resistance. This study compares the adhesive bond strength of these composites using sisal, jute, and hybrid mats joined ...

Failure Analysis of Brazed Joints Using the CZM Approach [PDF]
Brazing, as a type of joining process, is widely used in manufacturing industries to join individual components of a structure. Structural reliability of a brazed assembly is strongly dependent on the joint mechanical properties.

Modelling adhesive joints with cohesive zone models: effect of the cohesive law shape of the adhesive layer [PDF]
Adhesively-bonded joints are extensively used in several fields of engineering. Cohesive Zone Models (CZM) have been used for the strength prediction of adhesive joints, as an add-in to Finite Element (FE) analyses that allows simulation of damage growth,

Abstract Self‐healing concrete, with its ability to autonomously repair damages, holds promise in enhancing its structural durability and resilience. Research on self‐healing concrete in the past decade has advanced in understanding the mechanisms behind healing, exploring various healing agents, and assessing their effectiveness in concrete structures.

Computational model coupling mode II discrete fracture propagation with continuum damage zone evolution [PDF]
We propose a numerical method that couples a cohesive zone model (CZM) and a finite element-based continuum damage mechanics (CDM) model. The CZM represents a mode II macro-fracture, and CDM finite elements (FE) represent the damage zone of the CZM.

Numerical simulation of fatigue crack growth rate and crack retardation due to an overload using a cohesive zone model [PDF]
In this work, a numerical method is pursued based on a cohesive zone model (CZM). The method is aimed at simulating fatigue crack growth as well as crack growth retardation due to an overload.
