This project will use an ultrasonic beam traveling longitudinally along the rail rather that the complex normal and angle-beams transducer assemblies in current systems. Detection of transverse defects becomes a simple pulse-echo application and resolves many inherent speed, inspection reliability… More

This project will use an ultrasonic beam traveling logitudinally along the rail rather than the complex normal and angle-beams transducer assemblies in current systems. Detectio of transverse defects becomes a simple pulse-echo application and resolves many inherent speed, inspectin reliability and… More

Development of the basic EMAT-based transverse rail defect detector has progressed toward finished form, as envisioned in the original solicitation.  This modification is intended to produce a demonstrable version of a 2-rail detection system with automated signal interpertation.

The objective of the proposed work is to develop ultrasonic, non-contact, nondestructive testing technology for marine aluminum structures. Three novel approaches will be evaluated for the marine aluminum weld application. Technology selection will be based demonstrated defect sensitivity and… More

This SBIR Phase I research proposal will advance the state-of-the-art by transforming civil infrastructure maintenance from time based to condition based, advance the state-of-the art in Acoustic Emission (AE) technology from the existing legacy personal computer based platform to an autonomous… More

Commercially available inspection technology dedicated to Marine Aluminum Structure Inspection does not exist. While generic inspection technologies are being applied to this application, a transition to dedicated inspection technology is required to realize meaningful total ownership cost… More

This Small Business Innovation Research Phase I research project will advance the state-of-the-art in underwater bridge inspection through development of novel long range ultrasonic technology (LRUT). The objective of this project is to determine if the proposed technology can minimize the… More

Several critical components of a coal power plant that operate at high temperature and high pressures ¿ including boilers, high pressure pipelines, waterwall tubes, and boiler support structures ¿ are very susceptible to various time-dependant failure-causing mechanisms such as high… More

Current inspection, maintenance and lifetime estimation practices for composite cylinders have been adopted from earlier NASA research. WavesinSolids LLC are proposing a technological based on an acoustic emission (AE) technique for the in-service testing of composite cylinders. The approach will… More
