This article focuses on the peristaltic flow of carbon nanoparticle-suspended nanofluids under influence electroosmosis. The is considered inside a vertical tube with ciliated boundary walls. study holds great importance because it represents esophagus human body. Nanoparticles are inserted in blood for diagnosing diseases like cancer and also useful angiography, angioplasty, etc. A comparative...

We analyze the initiation and propagation of adiabatic shear bands in a thick-walled 4340 steel tube with a V-notch in the middle. The material is modeled as strain hardening, strain-rate hardening and thermal softening. The deformations are assumed to be locally adiabatic and the effect of inertia forces is considered. Two different loadings, i.e., torsional, and combined torsional and axial p...

Thin-walled tube bending is still to be considered a new and advanced technique. The process has been adopted into several industries such as aero and automotive. This process may produce a wrinkling, bulking and tearing phenomenon if the process parameters are inappropriate, especially for tubes with large diameter and thin wall thickness. Push bending process is one of the methods used for be...

Assessing the behavior of composite structures which are subjected to impact loads is one of the important subjects in the field of mechanical sciences. Using thin-walled tubes which collapsed and absorbed the impact energy is a well-known method to prevent damages to the other parts of the structures. In this paper, deformations, crushing length, peak load, mean force and energy absorption cap...

Energy absorber systems like metallic dampers for controlling the structural vibrations due to earthquake have witnessed considerable development in the past few decades. Also there are some studies on the energy absorption of thin-walled tubes due to impact load. Thin-walled tubes have a large deformation capacity and are suitable energy absorbers in the structure during an earthquake provided...

This paper reports dependency of specific heat and ballistic thermal conductance on cross-sectional geometry (tube versus rod) and size (i.e., diameter and wall thickness), in free-standing isotropic non-metallic crystalline nanostructures. The analysis is performed using dispersion relations found by numerically solving the Pochhammer-Chree frequency equation for a tube. Estimates for the allo...

Tube systems are widely used in heat transfer and intensive research is being done on positioning tubes a platform. The platform structure constantly exposed to thermal changes under operating conditions the resulting stresses cause damage existing systems. In this study, 8 thin-walled were positioned flat curved platforms that stress behavior effects was investigated. Finite element analysis u...

This paper evaluates three critical plane criteria, namely the Findley, Matake and modified Wöhler curve method compares them to IIW’s implementation of Gough–Pollard criteria. Assessment is conducted on a large set fatigue data thin-walled tube–tube laser beam welded specimens made magnesium aluminum alloys that were tested under proportional/non-proportional constant/variable amplitude loadin...
