This paper presents a three dimensional nonlinear finite element analysis for Concrete Filled Steel Tube (CFST) columns subjected to lateral impact load. The finite element models were developed using commercial code ABAQUS/Explicit, which were validated against the experimental results. The study has been carried out to examine the influence of several parameters such as the length of the tube...

Greenville Tube Company (GT), a manufacturer of high-precision, small-diameter stainless steel tubing, conducted an in-house system performance optimization project to improve the efficiency of its No. 6 tube drawing bench. This tube drawing bench plays an integral role in the production process, but severely hindered the productivity and energy efficiency of the facility. GT’s plant engineer, ...

This paper describes the fracture mechanics approach behind the water pressure ‘blow-off test for characterising the failure behaviour of composite repairs on steel tubes. The technique enables the fracture toughness of the metal/composite interface to be determined at the point where failure initiates. Surprisingly the values found for the interfacial fracture toughness are typically an order ...

In Ultrasonic Inspection, the first and foremost step to find the defects in welding materials used in industrial applications is Noise Reduction. It is used to improve the detect ability of the weld defects. It plays a vital role in Flaw Detection and Characterization of materials such as Austenitic Stainless Steels etc. This study gives a review of various noise reduction schemes or technique...

Laser Interferometer Gravitational-Wave Observatory ~LIGO! is a joint project of the California Institute of Technology and the Massachusetts Institute of Technology funded by the National Science Foundation. The project is designed to detect gravitational waves from astrophysical sources such as supernova and black holes. The LIGO project constructed observatories at two sites in the U.S. Each...
