Couple-stress–based gradient theory of poroelasticity

Mathematics and Mechanics of Solids, 2023
In this research, we present a gradient theory of poroelasticity based on the couple-stress. Within the context of finite deformations and in a thermodynamically consistent manner, the constitutive equations for the porous solid are derived by including the solid vorticity gradient and its power-conjugate counterpart, namely, the couple-stress ...

Flow analysis of biconvective heat and mass transfer of two-dimensional couple stress fluid over a paraboloid of revolution

, 2020
In this paper, two-dimensional non-Newtonian couple stress fluid flow over the upper horizontal surface of a paraboloid (uhsp) (shaped like a submarine or any aerodynamical automobile) is investiga...

Small-scale thermoelastic damping in micro-beams utilizing the modified couple stress theory and the dual-phase-lag heat conduction model

Journal of thermal stresses, 2019
In this article, the size-dependent behavior of micro-beams with the thermoelastic damping (TED) phenomenon is studied. The coupled thermoelasticity equations are derived on the basis of the modified couple stress theory (MCST) and dual-phase-lag (DPL ...

On the NURBS-based isogeometric analysis for couple stress-based nonlinear instability of PFGM microplates

Mechanics based design of structures and machines, 2020
A porosity-dependent nonlinear postbuckling analysis for microplates prepared from a porous functionally graded material (PFGM) is performed based on the modified couple stress theory of elasticity (MCSTE). To accomplish this purpose, the modified couple

Couple Stresses and More General Stresses

1978
Let dσ λ (u λ dσ λ = 0) represent the infinitesimal spatial oriented surface dσ through the event point E (or x ρ ) in the world tube WC of body C—cf. (24.1). We consider the forces exerted by the matter elements contiguous to the negative face of dσ on those contiguous to the positive one.

Stress in couples undergoing assisted reproductive technology

Archives of Gynecology and Obstetrics, 2020
To determine the associations between pre-treatment self-reported stress level, salivary cortisol levels, and clinical pregnancy outcome in couples undergoing assisted reproductive technology treatment (ART).Seventy-five couples (150 patients) undergoing ART treatment were enrolled in this study.
