Character of couple and couple-stress in continuum mechanics
Ali R. Hadjesfandiari
In this paper, the concept of moment and couple in mechanics is examined from a fundamental perspective. It turns out that although representing a couple by its moment vector is ve…
Finite element modeling of micropolar-based phononic crystals
Nicolás Guarín-Zapata, Juan Gomez, Camilo Valencia +2
The performance of a Cosserat/micropolar solid as a numerical vehicle to represent dispersive media is explored. The study is conducted using the finite element method with emphasi…
An assessment of higher gradient theories from a continuum mechanics perspective
Ali R. Hadjesfandiari, Gary F. Dargush
In this paper, we investigate the inherent physical and mathematical character of higher gradient theories, in which the strain or distortion gradients are considered as the fundam…
Fundamental governing equations of motion in consistent continuum mechanics
Ali R. Hadjesfandiari, Gary F. Dargush
We investigate the consistency of the fundamental governing equations of motion in continuum mechanics. In the first step, we examine the governing equations for a system of partic…
Consistent continuous defect theory
Ali R. Hadjesfandiari, Gary F. Dargush
By investigating the benefits and shortcomings of the existing form of continuous defect theory (CDT) and using recent advancements in size-dependent continuum mechanics, we develo…
Size-dependent couple stress Timoshenko beam theory
Ali R. Hadjesfandiari, Arezoo Hajesfandiari, Haoyu Zhang +1
In this paper, a new size-dependent Timoshenko beam model is developed based on the consistent couple stress theory. In the present formulation, the governing equations and corresp…
