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 ...
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 ...
Wear resistance investigation of titanium nitride-based coatings
(
Elsevier Ltd
, 2015 , Article)
The wear of components while they are in service is a predominant factor controlling the life of machine components. Metal parts are often damaged because of wear-driven failures causing the loss of dimensions and ...
Effect of microstructural evolution on wettability and tribological behavior of TiO2 nanotubular arrays coated on Ti–6Al–4V
(
Elsevier Ltd
, 2015 , Article)
Self-organized TiO2 nanotubular arrays were fabricated by electrochemical anodization of Ti–6Al–4V plates in an NH4F/H3PO4 electrolyte. The effect of microstructural evolutions on the wettability and tribological behavior ...
TiO2 nanotube coating on stainless steel 304 for biomedical applications
(
Elsevier Ltd
, 2015 , Article)
The present study describes the anodic growth of TiO2 nanotube thin layer on stainless steel 304 in ethylene glycol/water/ammonium fluoride electrolyte. In this regard, pure titanium was coated on stainless steel 304 ...
