Study of influence of various loading parameters on crack propagation by using Cohesive Zone Modeling (CZM) approach

Open Engineering, 2011
Abstract Cohesive Zone Modeling (CZM) is one of the most promising tools to investigate nonlinear crack propagation in present time. In this study, CZM approach is used to investigate the influence of various type of loading parameters in nonlinear crack propagation.

Simulasi Delaminasi pada Komposit Glass Fiber-reinforced Polymer (GFRP) dan Carbon Fiber-reinforced Polymer Menggunakan Metode Cohesive Zone Model (CZM) dan Virtual Crack Closure Technique (VCCT)

Jurnal Teknik ITS, 2020
Komposit digunakan untuk pengganti logam, dengan mempertimbangkan kekuatan yang tidak berbeda jauh dengan logam. Glass fiber-reinforced polymer (GFRP) dan carbon fiber-reinforced polymer (CFRP) merupakan dua komposit yang saat ini banyak digunakan. Namun pada penggunaannya komposit dapat mengalami kegagalan.

Experimental Study and Numerical Simulation Using Extended Finite Element Method (XFEM) Combined with Cohesive Zone Model (CZM), of Crack Growth Induced by Non-Explosive Expansive Material on Two Neighboring Circular Holes of A Gneiss Rock

Open Journal of Applied Sciences, 2020
The Non-explosive expansion material (NEEM) is a method more environmentally friendly than the harmful conventional rock fracturing techniques. However, it is slower and very costly. Thus, any means of economizing their use is very desirable.

Implicit DEM analyses of size and shape effects on crushing strength of rockfill particles

Yantu gongcheng xuebao, 2023
An implicit version of discrete element method (DEM) called non-smooth contact dynamics (NSCD) is used to simulate the crushing process of single rockfill particle under one-dimensional (1D) compression.

Numerical Simulation of Fracturing in Coals Using Water and Supercritical Carbon Dioxide with Potential-Based Cohesive Zone Models

Geofluids, 2021
The Park-Paulino-Roesler (PPR) cohesive zone model (CZM) for coal was established for analyzing mixed-mode I/II fractures using semicircular specimens under punch-through shear (PTS) and three-point bending (SCB) tests.

Numerical aspects of phase field models for low-temperature fracture in asphalt mixtures

Case Studies in Construction Materials, 2023
Unlike the cohesive interface element model, the phase field model (PFM) is a newly developed computational model which provides a unified approach to predicting crack nucleation, propagation, coalescence and branching without any ad-hoc criterion.
