Analyzing exact nonlinear forced vibrations of two-phase magneto-electro-elastic nanobeams under an elliptic-type force
(
Techno-Press
, 2020 , Article)
The present paper deals with analyzing nonlinear forced vibrational behaviors of nonlocal multi-phase piezo-magnetic beam rested on elastic substrate and subjected to an excitation of elliptic type. The applied elliptic ...
Nonlocal strain gradient effects on forced vibrations of porous FG cylindrical nanoshells
(
Techno-Press
, 2020 , Article)
The present paper explores forced vibrational properties of porosity-dependent functionally graded (FG) cylindrical nanoshells exposed to linear-type or triangular-type impulse load via classical shell theory (CST) and ...
Porosity effects on post-buckling behavior of geometrically imperfect metal foam doubly-curved shells with stiffeners
(
Techno-Press
, 2020 , Article)
This papers studies nonlinear stability and post-buckling behaviors of geometrically imperfect metal foam doubly-curved shells with eccentrically stiffeners resting on elastic foundation. Metal foam is considered as porous ...
Post-buckling analysis of geometrically imperfect nanoparticle reinforced annular sector plates under radial compression
(
Techno-Press
, 2020 , Article)
Buckling and post-buckling behaviors of geometrically imperfect annular sector plates made from nanoparticle reinforced composites have been investigated. Two types of nanoparticles are considered including graphene oxide ...
Magneto-electric effects on nonlocal nonlinear dynamic characteristics of imperfect multi-phase magneto-electro-elastic beams
(
Elsevier
, 2020 , Article)
This paper studies nonlinear dynamic characteristics of a nonlocal two-phase piezo-magnetic beam including geometric imperfections by considering piezoelectric reinforcement scheme. The piezoelectric reinforcement can cause ...
Mechanical and thermal stresses in a functionally graded rotating disk with variable thickness due to radially symmetry loads
(
Elsevier Ltd
, 2008 , Article)
Rotating disks have many applications in the aerospace industry such as gas turbines and gears. These disks normally work under thermo mechanical loads. Minimizing the weight of such components can help reduce the overall ...
Multiple parts process planning in serial-parallel flexible flow lines: part I—process plan modeling framework
(
Springer London
, 2015 , Article)
In recent years, integrated process planning and scheduling models have been proposed as solutions that can bridge the gap between practical process planning and production scheduling. However, most structures of these ...
Self-organized TiO2 nanotube layer on Ti–6Al–7Nb for biomedical application
(
Elsevier B.V.
, 2015 , Article)
In the present study, a self-organized nanotube TiO2 layer on Ti–6Al–7Nb was fabricated. The influence of acidic electrolytes including glycerol (G) and ethylene glycol (EG) on the anodization, microstructural features and ...
Dry sliding tribological properties of a hard anodized aa6082 aluminum alloy
(
MDPI AG
, 2020 , Article)
The applications of aluminum and its alloys are still limited by low hardness and low wear resistance properties. Surface modifications, such anodizing and plasma electrolytic oxidation, represent a feasible way to overcome ...
Engaging Engineering Students in Active Learning and Critical Thinking through Class Debates
(
Elsevier Ltd
, 2015 , Conference Paper)
Within the program of engineering, typically there are courses that are heavily dependent on mathematics and derivations of fundamental concepts. A lot of active learning can be done in these classes by using the engineering ...
