چکیده

This paper presents an overview of Laser Shock Processing and then discusses how the process can be extended to treat fastener holes on aging aircraft. The process is used to treat localized fatigue-critical areas by developing deep residual compressive stresses to inhibit the initiation and propagation of fatigue cracks. This feature can be applied to fastener holes in aircraft structures to determine whether the fatigue life associated with the failure in these areas can be increased.

Analytical study of seismic durability and its destructive effects on structures and distribution of accelerated seismic durability of Iran

Background and objective: Experience with past earthquakes and numerical analysis confirms that the durability of strong earth motion, significantly can affect the amount of failure of civil engineering systems. However, if the durability is related to a parameter which describes the intensity of the earth's motion, such as maximum velocity or maximum acceleration or spectral acceleration, then...

Novel Thermal Barrier Coatings Produced by Axial Suspension Plasma Spray

Ceramic Thermal Barrier Coatings (TBCs) on superalloy components are being used successfully in land-based gas turbine and aircraft engines. These coatings are generally made by either air plasma spraying (APS) or electron beam physical vapour deposition (EB-PVD). In general, EB-PVD TBCs have superior durability due to the columnar structure, but they are very expensive compared to APS TBCs. EB...

Energy Dissipation Capacity in MWCNTs Reinforced Metal Matrix Nanocomposites: An Overview of Experimental Procedure

Adsorption of vibration energy by mechanical damping is a significant problem in many engineering designs. High damping materials are used to reduce vibration in aircraft and other machinery. The benefits of damping treatment are advanced durability, reliability and service life of components, reductions in weight, noise and costs (Chung, 2001). By invoking the properties of nanostructures it m...
