FRICTIONAL DAMPING OF THE TIDE IN THE GULF OF CALIFORNIAFRICTIONAL DAMPING OF THE TIDE IN THE GULF OF CALIFORNIA
(Instituto de Geofísica, 2012)
Modeling of thermal cycles and microstructural analysis of pipeline steels processed by friction stir processing
(2018-10-01)
During friction stir welding or processing (FSP), temperature and deformation have influence on the final microstructure and mechanical properties. Studying microstructures before and after welding might help interpreting ...
Friction coefficient and abrasive wear modes in ball-cratering tests conducted at constant normal force and constant pressure-Preliminary results
(ELSEVIER SCIENCE SA, 2009)
The micro-scale abrasive wear test by rotative ball has gained large acceptance in universities and research centers, being widely used in studies on the abrasive wear of materials. Two wear modes are usually observed in ...
Limiting the influence of friction on the split Hopkinson pressure bar tests by using a ring specimen
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The deformation of a ring under axial compression is analyzed in order to estimate a favorable ring specimen geometry capable of limiting the influence of friction on the stress-strain curve obtained from SHPB tests. The ...
Thermal and friction drop characteristic of heat exchangers with elliptical tubes and smooth fins
(La Habana, 2013)
Pressure drop and heat transfer are the most important parameters in compact heat exchanger. There is a
lack of information in the literature about heat exchanger with elliptical tube. The objective of this work was
the ...
Friction Stir Welding Of Duplex Stainless Steels
(Associação Brasileira de SoldagemSão Paulo, 2016)
On the control of a non-ideal engineering system: A friction-driven oscillating system with limited power supply
(2003-01-01)
In this work a switching feedback controller for stick-slip compensation of a 2-DOF mass-spring-belt system which interacts with an energy source of limited power supply (non-ideal case) is developed. The system presents ...
Physical simulation as a tool to understand friction stir processed X80 pipeline steel plate complex microstructures
(2019-01-01)
The thermal cycles associated to friction stir welding and processing produce a wide range of microstructures, resulting in different mechanical behaviors along the weld. Most research efforts have focused on the development ...
Nonlinear ball and beam control system identification
(2014)
The Ball and Beam system is a common didactical experiment in control laboratories that can be used to illustrate many different closed-loop control techniques. The plant itself is subjected to many nonlinear effects, which ...
Sensitivity analysis and parameter estimation of heat transfer and material flow models in Friction Stir Welding
(Universidad Federal de Sao Carlos, 2014-11)
Although numerical models of heat transfer and material flow have contributed to understand the underlying mechanisms of friction stir welding (FSW), there are certain input model parameters that can not be easily determined. ...
