that the construction technique developed in the present investigation reflects the most economic approach, which reduces the nominal cost of such complex structures during construction.

Characterization of stiffened circumferentially cracked pipe with fiber reinforced polymer composite patch.Advanced Materials Letters, September 2013. Scopus Indexing. Abstract: In this work the fiber reinforced polymer FRP patch is utilized to restore damaged metallic pipe with outer part through circumferential crack. A circumferential patch was employed to cover the full surface of the pipe at the cracked area. Linear elastic fracture mechanics LEFM scheme and finite element method ware used to evaluate the stress intensity factor(SIF) and the crack opening displacement (COD) as characterizing parameters along the surface crack profile. ANSYS package was utilized in this study and 3D-20 nodes solid elements was adopted. Two loading conditions were investigated, that is, axial load and bending load. It was found that COD and hence the SIF reduced considerably in the vicinity of the crack tip using the stiffened technique. Keywords: Circumferential crack, FRP composite patch, Pipes, SIF, COD. The Impact of Embedded Non-inclusion in Nanofiber Reinforced Composite. Physical Review & Research International 3(4):438-451, 2013. Abstract: Studying the influence of a Nano-inclusion embedded in Nanofiber reinforced composite alongside a Nanofiber is the objective of the present investigation. The analysis is done based on 2D, linear elastic finite element through using finite element package ANSYS/Mechanical to explore the impact of the Nano-inclusion on the mechanical behavior of the Nanocomposite. Mainly, two scenarios are the major outlines of the study, first whenever the presence of the Nano-inclusion is located at the longitudinal side of the Nanofiber, whereas in the second case, the Nano-inclusion is proposed to be along the transverse side of the Nanofiber. The levels of the interfacial
