Discrete and Phase Field Methods for Linear Elastic Fracture Mechanics: A Comparative Study and State-of-the-Art Review

Applied Sciences, 2019
Three alternative approaches, namely the extended/generalized finite element method (XFEM/GFEM), the scaled boundary finite element method (SBFEM) and phase field methods, are surveyed and compared in the context of linear elastic fracture mechanics ...

Scaled Boundary Finite Element Method for Thermoelasticity in Voided Materials [PDF]

, 2015
The scaled boundary finite element method (SBFEM) is presented to study thermoelastic problems in materials with voids. The SBFEM combines the main advantages of the finite element method (FEM) and the boundary element method (BEM).

A combined virtual element method and the scaled boundary finite element method for linear elastic fracture mechanics [PDF]

, 2020
In this paper, we propose a framework that combines the recently introduced virtual element method (VEM) and the scaled boundary finite element method (SBFEM) to evaluate the fracture parameters.

The simulation of Lamb waves in a cracked plate using the scaled boundary finite element method [PDF]

, 2012
The scaled boundary finite element method is applied to the simulation of Lamb waves for ultrasonic testing applications. With this method, the general elastodynamic problem is solved, while only the boundary of the domain under consideration has to be ...

Flexural wave band gaps of steel bridge decks periodically stiffened with U-ribs: Mechanism and influencing factors

Journal of Low Frequency Noise, Vibration and Active Control, 2022
To effectively and efficiently control vibrations in steel bridge decks, the flexural wave band gap and vibration attenuation mechanism are studied. The band structures and displacement fields of the eigenmodes at the band gap edges of infinite periodic ...

Extension of the natural element method to surface tension and wettability for the simulation of polymer flows at the micro and nano scales [PDF]

, 2013
The natural element method is used to simulate two-dimensional viscous flows where interfacial effects must be taken into account, for application to polymer melts at the micro and nano scales.

Implementation of arbitrary polyhedral elements for automatic dynamic analyses of three-dimensional structures

Scientific Reports, 2022
The transition from the geometry to the mesh can be rather difficult, manual and time-consuming, especially for the large scale complex structures.
