Regional similarities in the distributions of well yield from crystalline rocks in Fennoscandia [PDF]

open access: yes, 2010
Well yields from Precambrian and Palaeozoic bedrock in Norway, Sweden and Finland exhibit very similar and approximately log-normal distributions: all three data sets exhibit a median yield of 600–700 L hr-1, despite the differences in climate and ...

Investigation on Plastic Flow Behaviors of FCC Polycrystalline Aluminum under Pre-Cyclic Tension-Compression Loading: Experiments and Crystal Plasticity Modeling

open access: yesNanomaterials, 2021
The plastic flow behaviors of FCC polycrystalline aluminum after pre-cyclic tension-compression deformation are mainly investigated in tension–torsion stress space by the physically based crystal plasticity model introducing a back-stress.

Evaluation method with finite-element analysis for bending rupture limit of line pipe with high design factor

open access: yesNihon Kikai Gakkai ronbunshu, 2016
This study focused on ruptures due to bending deformation of steel pipe that is operated with a high design factor. The design factor refers to the ratio of the hoop stress from internal pressure to the yield strength of pipe material.

Low secondary electron yield engineered surface for electron cloud mitigation [PDF]

open access: yes, 2014
Secondary electron yield (SEY or δ) limits the performance of a number of devices. Particularly, in high-energy charged particle accelerators, the beam-induced electron multipacting is one of the main sources of electron cloud (e-cloud) build up on the ...

Surface construction for orthrotropic perfectly elastic-plastic Murnaghan material

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2021
The problem of constructing a yield surface is described. The magnitude of the stress velocity potential is explained graphically. The parameters of an elastic-plastic process are introduced: a modified R.

Surface profile prediction and analysis applied to turning process [PDF]

open access: yes, 2008
An approach for the prediction of surface profile in turning process using Radial Basis Function (RBF) neural networks is presented. The input parameters of the RBF networks are cutting speed, depth of cut and feed rate.

Assessment of hydrology, sediment and particulate organic carbon yield in a large agricultural catchment using the SWAT model [PDF]

open access: yes, 2011
The Soil and Water Assessment Tool (SWAT, 2005) was used to simulate discharge and sediment transport at daily time steps within the intensively farmed Save catchment in south-west France (1110 km2).
