This paper presents a new type of eddy current transducer, send-receiver type, using the rotating magnetic field method. The forward problem was solved, the experimental results obtained for detection of different types of degradation have proved the capability to emphasize blisters, and garter springs location and tilt as well as hydrogen content. INTRODUCTION The nondestructive testing of met...

This paper presents the development and experimental validation of a multi-hazard bridge pier concept, i.e., a bridge pier system capable of providing an adequate level of protection against collapse under seismic and blast loading. A multi-column pier-bent with concrete-filled steel tube (CFST) columns is the proposed concept, and the adequacy of this system is experimentally and analytically ...

Three subjects, all smokers, handling stainless steel tubes suffered repeated attacks of general malaise, chills, and fever lasting for several hours, mainly after gas soldering. Provocations by rubbing smoking tobacco against a tube produced similar attacks, and leucocytosis, after a few hours. The presence of fluorine on the tubes and in the febrifacient tobacco was shown. A fluorocarbon poly...

An experimental investigation has been carried out to study the cooling of a hot horizontal Stainless Steel surface of 3mm thickness, which has 800±10°C initial temperature. A round water jet of 22 ± 1C temperature was injected over the hot surface through straight tube type nozzles of 2.5-4.8mm diameter and 250mm length. The experiments were performed for the jet exit to target surface spacing...

-This paper introduces an experiment to investigate dry sliding resistance of frictional interfaces at normal pressures up to 100 MPa, slip speeds up to 10 m/s and slip distances of approximately 10 mm. This new apparatus involves a novel modification of the conventional torsional Kolsky bar apparatus, employed extensively in the past for investigating high strain rate behavior of engineering m...
