Nonlocal Torsional Vibration of Nanorods
Abstract: Normal 0 false false false EN-US X-NONE X-NONE The present work deals with the torsional vibration of nanorods based on nonlocal elasticity theory. The nonlocal elasticity theory is incorporated into classical rod model to capture unique features of the nanorods under the continuum mechanics theory. The strong effect of the nonlocal scale has been obtained which leads to substantially different behaviors of nanorods from those of macroscopic rods. Nonlocal rod …

Few Aspects in Deep Drawing Process
Abstract: The process in which a punch forces a flat sheet metal blank into a die cavity is known as deep drawing. Deep Drawing (DD) is one of the sheet metal forming processes widely used in automobile, aerospace, electronics and allied industries to produce the hollow parts. Presently, the conventional deep drawing (CDD) operation is carried out at room temperature in industries. Although, CDD provides a great potential application for the …

Small Scale Horizontal Axis Wind Turbine
Abstract: In this work, the performance analysis of a designed small scale horizontal axis wind turbine (HAWT) has been presented and optimized by varying span length and chord length. The HAWT blades are shaped to generate maximum power from the wind at minimum cost. The blades are designed by using QBlade software and simulated in blade element method (BEM).The values of tip speed ratio and power coefficient have been obtained as …
