In recent years, weight reduction of automobiles is being achieved by using light weight metals like magnesium (Mg) in the form of cast or wrought products. However, the structural application of Mg and its alloys is limited ...

Friction plays a significant role in bulk plastic deformation processes in controlling the tool life, formability of the work piece material and the quality of the finished product such as, surface finish, microstructure ...

Liquid bridges, formed between two solid surfaces in close proximity are encountered in a variety of engineering and daily life applications. The dynamics of a liquid bridge including its evolution that typically involves ...

Vibration related issues like flutter can significantly limit the performance of aircraft engines and cause unwarranted cost and time overruns. The increased demand for more powerful yet compact engines has resulted in the ...

Manipulation of an array of sessile droplets organized in an ordered structure turns out to be of immense consequence in a wide variety of applications ranging from photonics, near field imaging and inkjet printing on one ...

Bistable arches have two force-free stable equilibrium configurations. They also show multimodality by switching between their stable states in multiple deformation pathways. These two attributes and their nonlinear ...

Closed-cycle gas turbines can complement conventional power conversion systems due to their potential for improved efficiencies, compact system layouts, and the ability to exploit non-fossil fuel energy sources which leads ...

Wall-bounded turbulent flows that possess finite curvature of the mean flow streamlines are known to be starkly different from their plane counterparts. One of the primary distinguishing features of such flows is the ...

High specific-strength materials with high toughness can reduce the weight of automobile and aerospace components. Lightweight components for these applications are essential, as they can significantly improve fuel efficiency. ...

Aluminium-copper joints are widely used in electrical applications due to their unique properties. However, joining of these metals by conventional welding techniques is restricted due to the formation of brittle (bulk ...
