Oxide Film Defects and Mechanical Properties in Aluminium Alloys
ISBN: 9783639711196 / Angielski / Miękka / 2014 / 332 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Double oxide films are significant defects in aluminium castings which were reported to have a detrimental effect on the reliability of the castings. This book reported the results of a research which was aimed at studying the behaviour of these defects in the liquid metal once they have formed. The results suggested that both oxygen and nitrogen inside the bifilm would be consumed by reaction with the surrounding melt, and that hydrogen might be diffused into the defect. The time required for the consumption of the atmosphere inside a defect entrained in pure Al, Al-7Si-0.3Mg and Al-5Mg...

Punching Shear Strengthening of Flat Slabs Using Ferrocement
ISBN: 9783659691737 / Angielski / Miękka / 2015 / 256 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Punching shear failure is a big issue in flat slab-column connections where the failure is a sudden and brittle. This research presents a proposed method for strengthening flat slab-column connections using ferrocement laminates. Both experimental and numerical investigations were carried out to study the effectiveness of this method in strengthening. An experimental program, ten square slabs with a concentric column was tested. Two specimens were kept as control specimens, and eight of them were strengthened with ferrocement laminates. The studied parameters were thickness of ferrocement...

Earthquake-Induced Structural Pounding
ISBN: 9783319163239 / Angielski / Twarda / 2015 / 156 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This books analyzes different approaches to modeling earthquake-induced structural pounding and shows the results of the studies on collisions between buildings and between bridge segments during ground motions. Aspects related to the mitigation of pounding effects as well as the design of structures prone to pounding are also discussed. Earthquake-induced structural pounding between insufficiently separated buildings, and between bridge segments, has been repeatedly observed during ground motions. The reports after earthquakes indicate that it may result in limited local damage in...
