In this paper, we present for the first time a size-dependent model based on the modified couple stress theory (MCST) and isogeometric analysis (IGA) for the static and free vibration …
In this article, a refined modified couple stress theory based on isogeomeric analysis to capture the small-scale effect on laminated composite micro-plates is developed for the first …
Since the classical continuum theory is neither able to evaluate the accurate stiffness nor able to justify the size-dependency of micro-scale structures, the non-classical continuum …
The main objective of this paper is to explore the linear and nonlinear responses of porous metal foam micro-plate using a modified couple stress theory coupled with isogeometric …

A new modified couple stress theory for anisotropic elasticity is proposed. This theory contains three material length scale parameters. Differing from the modified couple stress …

The size effect on orthotropic Kirchhoff-type skew micro-plates is investigated based on a modified couple stress theory. For a three-dimensional orthotropic body, three additional …
The aim of this paper is to numerically investigate the geometrically nonlinear primary resonance of third-order shear deformable functionally graded carbon nanotube reinforced …

In this study, a non-confirming element which is a combination of the BCIZ and refined triangular non-conforming element is developed for the free vibration analysis of micro-scale …
The classical continuum theory not only underestimates the stiffness of microscale structures such as microbeams but is also unable to capture the size dependency, a phenomenon …
