Analysis of the Tilted Shallow Wedge Problem in Couple-Stress Elasticity
(2021)The present work examines the problem of the tilted shallow wedge problem in the context of the generalized continuum theory of couple stress elasticity. The solution methodology is based on singular integral equations ... -
Buckling and classification of high-strength steel CHS tubular members under axial compression and bending
(2012)EN 1993-1-1 provisions classify high-strength steel CHS members with relatively low values of D/t ratio as Class 3 or 4, so that their strength is based on elastic behavior only, neglecting their capability of sustaining ... -
Buckling of clad pipes under bending and external pressure
(2011)The present paper concerns the structural behaviour of clad pipes. This is a double wall pipe, composed by two pipes that are in contact through an appropriate manufacturing procedure; a thick-walled carbon steel "outer ... -
Circular tunnel in a gradient elastoplastic rock mass
(2020)This paper attempts to study the mechanical behavior of an elastoplastic rock mass around an underground circular excavation by using gradient theory. The problem (in plane conditions) is reduced to that of a circular hole ... -
Closed-Form Solution of the Bending Two-Phase Integral Model of Euler-Bernoulli Nanobeams
(2022)Recent developments have shown that the widely used simplified differential model of Eringen’s nonlocal elasticity in nanobeam analysis is not equivalent to the corresponding and initially proposed integral models, the ... -
Comparison of magnitude of actions on track in high-speed and heavy-haul railroads
(2012)In modern high-speed railways the necessity for achieving low life-cycle costs has led to a well-compacted-almost undeflected-substructure. Applications of excellent quality substructure are encountered in the French network ... -
Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
Compression-only behavior: Effect of prestress and shell rheology on bifurcation diagrams and parametric stability of coated microbubbles in an unbounded flow
(2022)Lipid-shelled microbubbles exhibit a strain-softening behavior and thus are characterized by preferential excursion from equilibrium during expansion at insonation. However, experimental studies have reported a counterintuitive ... -
Cylindrical indentation in micropolar elasticity
(2022)Experiments existing in the literature present a scale dependence of the mechanical properties of certain materials. Such scale dependence is observable also in indentation experiments where the attained contact area and ... -
The dynamic response of stereocilia by a gradient elasticity model
(2016)In the inner ear, stereocilia are the mechanosensing organelles of hair cells which respond to fluid motion for the hearing function. Stereocilia are lined up in several rows of increasing height like a stair case. At the ... -
Economic growth, efficiency and environmental elasticity for the G7 countries
(2019)In this study the non-parametric method of Data Envelopment Analysis (DEA) is applied to determine the technical efficiency (TE) index of the G7 countries, when variable returns to scale (VRS) hold for the entire period ... -
The effect of smoking on exhaled carbon monoxide and arterial elasticity during prolonged surgical mask use in the COVID-19 era
(2022)[No abstract available] -
Effectiveness of different confining configurations of FRP jackets for concrete columns
(2019)This paper presents the results of an experimental investigation on the compressive strength of small scale concentrically axially loaded fiber-reinforced polymer (FRP) confined plain concrete columns, with cylinder concrete ... -
Finite element modeling to expand the UMCCA model to describe biofilm mechanical behavior
(2005)In order to understand the influence of biofilm's physical and microbiological structures on its mechanical behavior, a finite element model that describes the structural mechanics of a composite solid is linked to the ... -
Forecasting the residential water demand, balancing full water cost pricing and non-revenue water reduction policies
(2014)The paper examines the factors that determine the residential water demand level in the city of Kozani located in the NW part of Greece. Based on an 8-year (2005-12) detailed sample of residential water demand time panel ... -
Gradient elasticity and size effect for the borehole problem
(2018)It has been shown recently that robust gradient models of elasticity offer an effective tool to resolve existing difficulties (e.g., elimination of singularities) or predict new experimentally observed phenomena (e.g., ... -
Influence of the track's stiffness coefficient on the acting loads, deflection and dimensioning of slab track
(2011)Slab Track, as all railway structures, should provide secure train running and smooth passenger ride. Moreover, it should present sufficient vertical elasticity to distribute the loads to the adjacent fixing points of the ... -
Instrumented indentation of a non-equal biaxial prestretched hyperelastic substrate
(2016)The present work investigates the instrumented indentation of a prestretched hyperelastic substrate. The substrate is incompressible and has an elastic energy density which is isotropic in the reference frame. The analysis ... -
The joint effect of water price changes and pressure management, at the economic annual real losses level, on the system input volume of a water distribution system
(2015)This study attempts to examine the factors affecting the residential water demand level in the city of Kozani in Greece. Based on an 8-year (2005-12) detailed sample of residential water demand panel data, the values of ... -
Joint Strength or "Efficiency" Factors of Steel Lap Welded Joints for Use in Water Conveyance
(2019)Joint "efficiency" factors are proposed for pressure vessels, piping, and pipelines by ASME standards. For the particular case of non-radiographically-tested lap-welded joints, a low value of joint "efficiency" is proposed. ...
