A model of lung surfactant dynamics based on intrinsic interfacial compressibility
(2021)A minimum model for the description of lung surfactant dynamics during consecutive compression/relaxation cycles is proposed. The model is based on Frumkin/Langmuir equilibrium and on an equation of state that includes ... -
Modeling atomic force microscopy and shell mechanical properties estimation of coated microbubbles
(2020)We present an extensive comparison with experimental data of our theoretical/numerical model for the static response of coated microbubbles (MBs) subject to compression from an atomic force microscope (afm). The mechanics ... -
Non-local criteria for the borehole problem: Gradient Elasticity versus Finite Fracture Mechanics
(2022)Two nonlocal approaches are applied to the borehole geometry, herein simply modelled as a circular hole in an infinite elastic medium, subjected to remote biaxial loading and/or internal pressure. The former approach lies ... -
Pretwisted beam subjected to thermal loads: A gradient thermoelastic analogue
(2017)It is well known from the classical torsion theory that the cross section of a prismatic beam subjected to end torsional moments will rotate and warp in the longitudinal direction. Rotation is depicted through the angle ... -
Pretwisted beams in axial tension and torsion: Analogy with dipolar gradient elasticity and applications to textile materials
(2015)A technical theory for pretwisted beams that accounts for variable twist (constrained warping) is based on an approximate displacement field that is defined completely in terms of two unknown functions: the axial displacement ... -
SANICLAY: A new simple anisotropic clay plasticity model
(2007)SANICLAY is a new simple anisotropic clay plasticity model that builds on a modification of an earlier model with an associated flow rule, in order to include simulations of softening response under undrained compression ... -
A second gradient elasto-plastic model for fatigue of small-scale metal components
(2010)Purpose - As the dimensions of structures are scaled down to the micro- and nano-domains, the mechanical behavior becomes size dependent and thus, the classical elasticity solutions cannot be expected to hold. In particular, ... -
Size effects in two-dimensional layered materials modeled by couple stress elasticity
(2021)In the present study, the effect of material microstructure on the mechanical response of a two-dimensional elastic layer perfectly bonded to a substrate is examined under surface loadings. In the current model, the substrate ... -
STRUCTURAL RESPONSE OF SUBSEA PIPE ELBOWS UNDER MONOTONIC AND CYCLIC LOADING
(2022)Pipe bends (elbows) are commonly used components in subsea piping systems. They are quite flexible compared to the corresponding straight pipes and are used to reduce the reaction forces and moments at the supports and the ... -
Ultimate capacity of pressurized 90 DEG elbows under bending
(2004)In this paper the response of internally pressurized pipe elbows under bending loads (in-plane and out-of-plane) is examined. The investigation is conducted through advanced finite element analysis tools, supported by ... -
Underground circular openings in elastoplastic rocks: Strain gradient and size effects
(2020)A special form of gradient elasticity and a deformation version of gradient plasticity are employed to derive analytical solutions for the problem of an unsupported underground circular opening in an elastoplastic rock ... -
Viscoelastic dynamic arterial response
(2017)Background Arteries undergo large deformations under applied intraluminal pressure and may exhibit small hysteresis due to creep or relaxation process. The mechanical response of arteries depends, among others, on their ... -
A von Karman plate analogue for solving anti-plane problems in couple stress and dipolar gradient elasticity
(2018)The purpose of the present work is to present a direct analogy regarding the formulation and solution of anti-plane problems in the context of couple stress and dipolar gradient elasticity and the von Karman plate framework. ... -
Wrinkling of lined pipes under bending
(2012)The present study is motivated by the use of lined pipes in energy pipeline applications (oil, gas, etc.) where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on ... -
Wrinkling of lined steel pipes under bending
(2013)Lined pipes are used in energy pipeline applications (oil, gas, etc.); a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on wrinkling of lined pipes (sometimes also ...
