Investigating the potential of magnetic are oscillated GMWA - welding for hard surfacing applications
(Pontificia Universidad Católica del Perú, 2015-08-19)
The flux cored arc welding process has some characteristic features and is therefore
established in the industry to fabricate hardfacing. One advantage of the process is the
possibility to vary the alloy content of the ...
Schwingunesverhalten von Spinnennetzen
(Pontificia Universidad Católica del Perú, 2015-08-12)
Wissenschaftliche Arbeiten zeigen einen Zusammenhang zwischen der Eigenfrequenz des
Spinnennetzes, dessen Geometrie, dem Eigengewicht der Netzspinne und der äquivalenten
Vorspannung. Hypothese dieser Masterarbeit ist, dass ...
Tracking controller design for a nonlinear model of a gantry crane based on dynamic extension and robustification
(Pontificia Universidad Católica del Perú, 2015-11-19)
Overhead cranes are widely used in industry for transportation of heavy loads and are
common industrial structures used in building construction, factories, and harbors,
traditionally operated by experienced crane operators. ...
Development of friction stir processing of CNT - reinforced aluminum alloy composites
(Pontificia Universidad Católica del Perú, 2015-08-12)
Owing their wide range of exceptional properties, for example thermal conductivity values of
more than 3000W/(mK) and strength in the range of 100 GPa, Carbon Nanotubes (CNTs) have
recently gained much attention as ...
Das Stoßspektrum von Spinnennetzen
(Pontificia Universidad Católica del Perú, 2015-08-19)
Die vorliegende Arbeit präsentiert Grundlagen, Versuchstechniken und neue Erkenntnisse des Systems Spinnennetz. Die bereits vorhandenen Kenntnisse über dieses Vorbild aus der Natur werden erweitert und bemerkenswerte ...
Laser-assisted friction stir welding of magnesium and magnesium/aluminium dissimilar joints
(Pontificia Universidad Católica del Perú, 2015-08-20)
The present master thesis is dealing with the influence of workpiece temperature in the process loads, generated during the FSW process. The investigation is focused on welding of the magnesium alloy AZ31. To affect the ...
