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 ... -
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 ... -
Mixed finite-element formulations in piezoelectricity and flexoelectricity
(2016)Flexoelectricity, the linear coupling of strain gradient and electric polarization, is inherently a size-dependent phenomenon. The energy storage function for a flexoelectric material depends not only on polarization and ... -
A non-local plasticity model for porous metals with deformation-induced anisotropy: Mathematical and computational issues
(2021)A non-local (gradient) plasticity model for porous metals that accounts for deformation-induced anisotropy is presented. The model is based on the work of Ponte Castañeda and co-workers on porous materials containing ... -
A procedure for factoring and solving nonlocal boundary value problems for a type of linear integro-differential equations
(2021)The aim of this article is to present a procedure for the factorization and exact solution of boundary value problems for a class of n-th order linear Fredholm integro-differential equations with multipoint and integral ... -
Results on the viscous slip coefficient for binary gas mixtures
(2008)The viscous slip coefficients for the binary gas mixtures of Ne-Ar, He-Ar and He-Xe are estimated by solving the McCormack kinetic model equation subject to Maxwell diffuse-specular scattering boundary conditions. The ... -
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 ... -
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 ...
