In this study, thermo-mechanical nonlinear vibration of a polyethylene (PE) cylindrical shell embedded in an elastic foundation was investigated. The shell is reinforced by armchair Carbon nanotubes (CNTs) where characteristics ...

Abstract: Application of atomic force microscope as a manipulator for pushing-based positioning of nano-particles has been of considerable interest during recent years. However a detailed modeling of the interaction forces ...

This paper deals with volume fraction optimization of Functionally Graded (FG) beams resting on elastic foundation for maximizing the first natural frequency. The two-constituent functionally graded beam consists of ceramic ...

Free vibration of simply supported circular cylindrical shell made of Functionally Graded Material (FGM) under internal pressure was investigated. The effective material properties are assumed to vary continuously along ...

This paper has focused on vibration and buckling of thin rectangular plates when at least two opposite sides are simply supported condition and subjected to axial and biaxial initially stresses. Analysis is based on exact ...

Using piezoelectric patches the stress concentration around a hole on a plate under tension is reduced and controlled. To attain the reduction in stress two placements for piezoelectric patches is investigated. The first ...

The current study presents a new analytical method for buckling analysis of circular plates with constant thickness and Poisson’s ratio, made of functionally graded material subjected to radial load. Governing equations ...

Abstract: Friction stir welding, a solid state innovative joining technique, is widely being used for joining aluminium alloys for aerospace, marine automotive and many other applications of commercial importance. FSW ...

In this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. Then, two-stage configuration of organic rankine cycle ...

The integration of an approximate model and a clonal selection algorithm (CSA) is considered to one of the most effective ways to solve complex optimization design problems in engineering. In this study, first, a process ...

An elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. A shape genetic algorithm optimization problem ...

In this work, the influence of different EDM parameters (pulse current, pulse voltage, pulse on-time , pulse off-time) in finishing stage on  the surface roughness (Ra)  as a result of application copper electrode to a ...
