Journal Article
Davoudi Kashkoli, M., & Nejad, M. Z. (2015). Time-dependent thermo-elastic creep analysis of thick-walled spherical pressure vessels made of functionally graded materials. Journal of Theoretical and Applied Mechanics, 53(4), 1053-1065. https://doi.org/10.15632/jtam-pl.53.4.1053

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
Rakhtala, S. M., & Shafiee Roudbari, E. (2016). Fuzzy PID control of a stand-alone system based on PEM fuel cell. International Journal of Electrical Power and Energy Systems, 78, 576-590. https://doi.org/10.1016/j.ijepes.2015.12.003

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
Mahmoudi, A., Ghasemi, A., Farrahi, G., & Sherafatnia, K. (2016). A comprehensive experimental and numerical study on redistribution of residual stresses by shot peening. Materials and Design, 90, 478-487. https://doi.org/10.1016/j.matdes.2015.10.162

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...

Influence of asymmetrical cuts in measuring residual stresses using contour method (2015)
Journal Article
Mahmoudi, A., & Saei, A. (2015). Influence of asymmetrical cuts in measuring residual stresses using contour method. International Journal of Pressure Vessels and Piping, 134, 1-10. https://doi.org/10.1016/j.ijpvp.2015.08.004

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...
