Ductile to brittle failure transition of HSLA-100 steel at high strain rates and subzero temperatures (2016)
Journal Article

Mechanical properties of HSLA-100 steel at room and subzero temperatures of −40 °C, −80 °C and −196 °C were investigated in this work. Dry ice and liquid nitrogen were used to reach the low temperatures. Also, the material response to different strai...

Experimental measurement and analytical determination of shot peening residual stresses considering friction and real unloading behavior (2016)
Journal Article

This paper presents an analytical model to predict the residual stress distribution induced by Shot peening. The analytical approach is based on the work of Shen and Atluri (2006) [18] with some modifications. The modifications are related to the ela...

Power budget analysis of fiber optics communication links along Benin-Asaba route (2016)
Journal Article

With the development of optical fiber communication system most telecommunication companies now prefer to use optical fiber transmission medium for higher information bandwidth. The design of such a system involves many aspects such as the type of so... Read More about Power budget analysis of fiber optics communication links along Benin-Asaba route.

Time-dependent thermo-elastic creep analysis of thick-walled spherical pressure vessels made of functionally graded materials (2015)
Journal Article

Assuming that the thermo-elastic creep response of the material is governed by Norton's law and material properties, except Poisson's ratio, are considered as a function of the radius of the spherical vessel, an analytical solution is presented for c...

Fuzzy PID control of a stand-alone system based on PEM fuel cell (2015)
Journal Article

Fuel cell (FC) systems are appropriate candidates as alternative energy sources for use in stand-alone applications. However, the FC generates an unregulated voltage, which is not suitable in stand-alone application usage solely. This paper presents...

A comprehensive experimental and numerical study on redistribution of residual stresses by shot peening (2015)
Journal Article

Shot peening is one of the most effective surface strengthening treatment technologies in which compressive residual stresses are induced beneath the specimen surface. Effects of various factors on the distribution of residual stress profile induced...

Spherical indentation, part II: Experimental validation for measuring equibiaxial residual stresses (2015)
Journal Article

It is occasionally important or even inevitable to measure residual stresses without harming engineering components. Spherical indentation can be categorized as a nondestructive method to measure residual stresses, as it causes very little damage to...

Stress variations effect on the accuracy of slitting method for measuring residual stresses (2015)
Journal Article

To maintain the structural integrity of the engineering components, having an exact knowledge of residual stresses is important. Among all mechanical strain relief techniques to measure residual stresses, slitting is one of the youngest. This techniq...

Influence of asymmetrical cuts in measuring residual stresses using contour method (2015)
Journal Article

Experimental methods to determine residual stresses are mainly divided into destructive and non-destructive categories. Contour method is a destructive technique that offers a two dimensional map of normal component of residual stresses. The conventi...
