Behavior of Axially Moving Nanobeams With Transverse Oscillation
ISBN: 9783659315565 / Angielski / Miękka / 2012 / 60 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Transverse free vibrations of axially moving nanobeams subjected to axial tension are studied based on nonlocal stress elasticity theory. A lower and higher-order differential equation of motion is derived from the D'Alembert principle with corresponding lower-order and higher-order, non-classical boundary conditions. Effects of nonlocal nanoscale, dimensionless axial velocity, density and axial tension on natural frequencies are presented and discussed through numerical examples for both lower and higher order differential equation of transverse motion. It is found that these factors have...

Properties of Mechanized Bricks and Performance as a Masonry Building
ISBN: 9783659406959 / Angielski / Miękka / 2015 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The efficiency of improving the seismic resistance of masonry buildings by means of materials and bands are done in this work. A series of experimental tests are conducted on mechanized bricks units in laboratory to check the properties of bricks and bricks units. After all the tests it is found that, the compressive strength of mechanised brick prism is increased by 47.80% over the manual clay bricks. The modulus of elasticity is increased by 29.13%, over the manual bricks and shear strength of mechanised bricks is also increased. The experimental study has also been made to assess the...
