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

Multiple Models of European Marine Fish Stocks: Regional Winners and Losers in a Future Climate. [PDF]
Glob Chang BiolUsing state‐of‐the art models we projected changes for 17 key commercial fish species in the Northeast Atlantic under two climate scenario. Carrying the analysis at the species level and regional scale rather than the usual total biomass approach, we identify “winners and losers” for fish and regional fisheries, highlighting the need for novel approach

Top-Down and Bottom-Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology. [PDF]
Ecol LettThis study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

Multiple crack propagation by DBEM in a riveted butt-joint: a simplified bidimensional approach [PDF]
Fracture and Structural Integrity, 2016 A Multi-Site Damage (MSD) crack growth simulation is presented, carried out by means of Dual Boundary Element Method (DBEM), in a two-dimensional analysis of a cracked butt-joint made of aluminium 2024 T3.

Predicting the impact of climate change on threatened species in UK waters. [PDF]
PLoS One, 2013 Global climate change is affecting the distribution of marine species and is thought to represent a threat to biodiversity. Previous studies project expansion of species range for some species and local extinction elsewhere under climate change.

FM-DBEM Simulation of 3D Microvoid and Microcrack Graphite Models [PDF]
Science and Technology of Nuclear Installations, 2017 The graphite is porous medium, and the geometry and size distribution of its structural deficiencies such as microcracks and microvoids at different oxidation degrees have a great influence on the overall performance.

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

DBEM crack propagation in friction stir welded aluminum joints
Advances in Engineering Software, 2016 This paper deals with the simulation of multiple crack propagation in friction stir welded butt joints and the aim is to assess the influence of process induced residual stresses on the fatigue behavior of the assembly. The distribution of the process induced residual stresses is mapped by means of the contour method; then, the computed residual stress

Efficient FEM-DBEM coupled approach for crack propagation simulations
Theoretical and Applied Fracture Mechanics, 2017 Abstract The paper deals with a FEM-DBEM hybrid methodology applied to crack propagation simulations. The method allows to simulate cracks propagation by means of Finite Element Method (FEM) and Dual Boundary Element Method (DBEM), coupled in a procedure that optimise computational effort and accuracy.

Residual strength evaluation by DBEM for a cracked lap joint
Fracture and Structural Integrity, 2015 The present work summarizes a numerical procedure aimed at the evaluation of the residual strength of a cracked lap joint, based on the competing failure mechanisms regulated by the R-curve analysis and plastic collapse.
