DBEM crack propagation for nonlinear fracture problems [PDF]
Fracture and Structural Integrity, 2015 A three-dimensional crack propagation simulation is performed by the Dual Boundary Element Method (DBEM). The Stress Intensity Factors (SIFs) along the front of a semi elliptical crack, initiated from the external surface of a hollow axle, are calculated

Wave attenuation by inclined porous plates using dual boundary element method
International Journal of Naval Architecture and Ocean Engineering, 2023 In this study, the wave attenuation by the inclined porous plates has been evaluated through a numerical approach. As a numerical method, we used the dual boundary element method (DBEM) that solves two distinct boundary integral equations (singular and ...

Multi-axial fatigue numerical crack propagations in cruciform specimens
Fracture and Structural Integrity, 2019 Two cracks, initiated from the opposite tips of a central notch inclined by 45䒰, were considered in cruciform specimens made of Ti6246. A static load was applied to a cruciform arm while a cyclic load was applied along the other arm.

Dynamic analysis of 2-D and 3-D quasi-brittle solids and structures by D/BEM [PDF]
Theoretical and Applied Mechanics, 2002 A general boundary element methodology for the dynamic analysis of 2-D and 3-D solids and structures exhibiting quasi-brittle material behavior is presented. Inelasticity is modeled with the aid of the elastic damage theory.

Hydrodynamics of an U-shaped OWC device in a two-layer fluid system
Energy Reports, 2022 In this article, the effectiveness of an U-shaped “oscillating water column wave energy converter device (OWC-WEC)” is investigated in a two-layer fluid system. To solve the BVP, the “dual boundary element method” (DBEM) is employed.
