In this article, the influence of various vacancy defects on the Young’s modulus of carbon nanotube (CNT) - reinforcement polymer composite in the axial direction is investigated via a structural model in ANSYS software. Their high strength can be affected by the presence of defects in the nanotubes used as reinforcements in practical nanocomposites. Molecular structural mechanics (MSM)/finite ...

OBJECTIVES The resin-bonded fixed partial dentures have gained immense popularity in recent years as they are more conservative, esthetic, economic and easily fabricated. However debonding is considered the most common cause of failure of resin bonded prosthesis. The objective of the study were to compare the effects of different groove lengths and thickness of retainers on retention of maxilla...

Abstract The approach for seismic strengthening of RC frames using moment redistribution and externally bonded FRP is especially applicable enhancing the performance a building that designed prior to introduction new codes. design detailing requirements these categories were conducted following capacity principle. Based on more recent codes, buildings are under-designed, has become mandatory. A...
