Crack propagation calculations in aircraft engines by coupled FEM-DBEM approach [PDF]
, 2012 New generation jet engines are subject to severe reduced fuel consumption requirements. This usually leads to thin components in which damage issues such as thermomechanical fatigue, creep and crack propagation can be quite important. The combination of stresses due to centrifugal loads and thermal stresses usually leads to mixed-mode loading ...

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 ...

dbEM: A database of epigenetic modifiers curated from cancerous and normal genomes. [PDF]
Sci Rep, 2016 AbstractWe have developed a database called dbEM (database of Epigenetic Modifiers) to maintain the genomic information of about 167 epigenetic modifiers/proteins, which are considered as potential cancer targets. In dbEM, modifiers are classified on functional basis and comprise of 48 histone methyl transferases, 33 chromatin remodelers and 31 histone

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.

Fatigue crack growth simulation using the moving mesh technique
Fatigue &Fracture of Engineering Materials &Structures, Volume 46, Issue 12, Page 4606-4627, December 2023., 2023 Abstract This work proposes a finite element (FE)‐based numerical model that uses the moving mesh technique for simulating fatigue crack propagation phenomena inside material components subjected to cyclic loads. Precisely, the computational mesh is adjusted during the numerical simulation according to conditions dictated by the criteria of fracture ...
