A Multimodal Acoustic Tool for Inline Pipe Inspection 3/19/2018 The US energy transport pipeline system is a longstanding distribution network with most of its still standing pipes being installed between the 1950s–1970s. Due to degradation mechanisms, such as embrittlement, capable of causing a two-fold reduction in fracture toughness, pipe rupture is a major risk. Current nondestructive ins ...

Proposal title: Rapid Assessment of Air Void System in Fresh Concrete Water expansion during freeze-thaw cycles can cause deterioration in concrete, leading to scaling, cracking, and crumbling over a period of years. Resistance to this damage is achieved with a system of voids formed by adding surfactants to the fresh concrete to stabilize air bubbles naturally entrained during mixing. The volume ...

Proposal title: Broken Rail Detection from Flashing Rear End Device Broken rails are a common cause of mainline derailments and a particular concern given the increasing use of our rail system for passenger traffic and petroleum products. The progressive nature of the defects provides an opportunity for early detection of cracks before they become significant enough to cause a derailment. Unfortu ...

FLAME RETARDANT FLEXIBLE POLYURETHANE FOAM FINDS WIDESPREAD COMMERCIAL USE AS A SEATING MATERIAL DUE TO ITS FAVORABLE COST, SUPPORT, AND RESILIENCE CHARACTERISTICS. HOWEVER, SMOKE AND TOXIC GAS EVOLUTION IN THE EVENT OF FIRE IS A MAJOR PROBLEM. THE GOAL OF THIS PROGRAM IS TO CREATE A FIRE RESISTANT COMPOSITE FOAM STRUCTURE WHICH WILL GENERATE NEGLIGIBLE QUANTITIES OF TOXIC FUMES WHEN EXPOSED TO FI ...
