1. Monitoring of Pipe-Wall Thickness and Thinning Rate by Ultrasonic Technique

Farzaneh Salehi; Farhang Honarvar; Anthony N Sinclair

Volume 5, Issue 4 , September 2012

Abstract
  An important issue in power generation and petrochemical industries is the monitoring of pipe wall thickness and corrosion/erosion rate. The pipes are usually subject to erosive and/or corrosive environments and any failure could be catastrophic. While periodic manual ultrasonic thickness measurement ...  Read More

2. An anisotropic axisymmetric model for wrought magnesium alloys

mohamad ali khayamian; hamid jahed

Volume 5, Issue 4 , September 2012

Abstract
  The global environmental concerns have put the light weighting of structures on the fore front of the research in transportation industry. Among other light weight alloys, the transportation industry is considering magnesium intensive light body-in-white structure in automotive applications. Although ...  Read More

3. Effect of Post-Cure Time on Residual Stress Distribution in Carbon/Epoxy Laminated Composites

Mahmood Mehrdad Shokrieh; Saeed Akbari Roknabadi

Volume 5, Issue 4 , September 2012

Abstract
  This research investigates the effect of the post-cure time on the residual stresses in laminated composites. Laminated composites were made of T300 carbon fibers and epoxy resin. The post-cure process was carried out at the constant temperature of 120 °C for 6 and 12 hours for two specimens. The slitting ...  Read More

4. Experimental Versus Numerical Investigation into the Effects of Hoop Welding in Metallic Pressure Vessels with Spherical Caps

Jaber Mirzaei; GH Rahimi; Saleh Yazdani

Volume 5, Issue 4 , September 2012

Abstract
  In this paper, an experimental and numerical investigation into the effect of the hoop welding in metallic pressure vessel is presented. In the experimental manufacturing, hoop welding was used to attach the cylindrical body of the vessel, and the effect of welding into stress and strain distribution ...  Read More

5. Triaxiality factor and Lode angle effects on failure of a steel considering plastic anisotropy

Giuseppe Mirone; Arash Keshavarz; Rahmatollah Ghajar

Volume 5, Issue 4 , September 2012

Abstract
  X-100 steel is one of the most recently developed materials for production of gas transportation pipelines. This material is severely anisotropic. Smooth and notched round bars with different notch radius and flat notched specimens with different notch radius and notch depth in tension are tested to ...  Read More

6. The Strain Rate Effect on Bending Properties of Basalt and Carbon Fibers Reinforced Phenolic Composites

Moslem Najafi; Seyyed Mohammad Reza Khalili; Reza Eslami-Farsani

Volume 5, Issue 4 , September 2012

Abstract
  In this study, the strain rate effect on the bending properties of fiber reinforced composites for three types of polymer composites namely phenolic resin reinforced by woven basalt fibers, woven carbon fibers, and woven basalt/ woven carbon fibers at a total volume fraction of approximately 35% has ...  Read More

7. Crack Identification of a Continuous Beam Like Structure in the Presence of Uncertain Modal Data by Stochastic Model Updating

yahya khatami; hamid ahmadian

Volume 5, Issue 4 , September 2012

Abstract
  The problem of crack identification in continuous beam like structures is considered. The cracks’ locations and their depths are identified by employing experimental modal test results performed on the structure. The cracks are modeled using generic elements to include the coupling effects between ...  Read More

8. A New Approach for Non Contact Measuring of Tension in Fixed and Moving Wires

Hooman Banitalebi; Mansour Rafeeyan; Ehsan khodaei

Volume 5, Issue 4 , September 2012

Abstract
  In this paper, based on equations of lateral vibrations of wires, a non contact method for measuring instantaneous tension in a wire is introduced. The lateral vibration of the string is measured using an eddy current transducer and is sent to a computer. This signal is then imported to suitable software ...  Read More

9. Bending Properties of Date Palm Fiber and Jute Fiber Reinforced Polymeric Composite

Mahmoud Asadzadeh; s.mohamad reza khalili; reza eslami farsani; siamak rafizadeh

Volume 5, Issue 4 , September 2012

Abstract
  In this research work, the effects of natural fibers such as date palm fiber (DF) and jute fiber (JF) on bending properties of polypropylene (PP)/ ethylene–propylene–diene–monomer (EPDM) thermoplastic elastomers are investigated. For this purpose, the date palm and jute fibers at five levels of ...  Read More

10. Investigation of rail track vibration due to fractured sleepers

Hosein Mortezaei; Mohamad Mahdi Jalili; Mohammad Taghi Ahmadian

Volume 5, Issue 4 , September 2012

Abstract
  In this paper effects of fractured sleepers on rail track vibration under moving wheelset have been investigated. Two parallel rails of the track have been modeled as Euler-Bernoulli beams on elastic points as rail pads. Also sleepers have been modeled as visco-elastic Euler-Bernoulli beams. It is assumed ...  Read More

11. Experimental and Numerical Study of Through Thickness Residual Stresses Distribution in Sheet Metals Produced by ECAR

Mohammad Sedighi; Masoud Mahmoodi

Volume 5, Issue 4 , September 2012

Abstract
  Abstract:The equal channel angular rolling (ECAR) is one of the severe plastic deformation processes, which can develop a shear deformation into a sheet metal. In this process, internal stresses are created due to the different strain levels experienced in different locations at the same time. The incremental ...  Read More
