Hollow cylindrical and truncated conical shells depict enhanced torsional shear resistance compared to beams plates are ubiquitously used in structures aeronautics, submarines, wind turbines, pressure vessels, transmission pylons. Upon extensive localised blast, these elements undergo local global deformation failure. The detrimental damage the shell depends on stand-off charge mass is proporti...

We describe computational modeling of flaring horns and piecewise conical bores using “Truncated Infinite Impulse Response” (TIIR) digital filtering techniques. The approach yields highly efficient and accurate computational models and is therefore appropriate for real-time simulations of woodwind and brass musical instruments.

Controlling the wettability using microstructures has been studied because of many applications. In particular, bio-mimetic modeled after self-cleaning properties lotus leaf have extensively studied. Despite studies successfully achieving fabrication superhydrophobic to superhydrophilic surfaces through manipulation microstructures, effect rough on contact angle remains an area inquiry. this st...

The present study aims at investigating stress and deformation behavior of rotating thick truncated conical shells subjected to variable internal pressure. Material prpperties of the shells are graded along the axial direction by Mori-tanaka scheme, which is achieved by elemental gradation of the properties.Governing equations are derived using principle of stsionary total potential (PSTP) and ...
