This Phase I and II SBIR will develop a user-friendly, run-time efficient software package dedicated to fitting and evaluating material models used in finite element codes like LS-DYNA. The software package will consist of a pre-processor, a core driver, and a post-processor. The pre-processor will allow the user to specify the material model, model parameters, and desired load history. The dri ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

Digital Wave Corporation proposed to develop a novel nondestructive testing (NDT) system for high speed acquisition and analysis of wide band acoustic emission (AE) waveforms. The system will provide the capability to detect, identify and locate crack growth in loaded steel structures. This system will incorporate the new high fidelity sensor developed by the Federal Highway Administration and a ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...

Passenger safety concerns have prompted the FAA to elicit energy-sensitive neutron detectors which do not rely on the time-of-flight method and are suitable for use in explosive detection systems. Invocon, Inc. proposes to design an inspection system consisting of an energy source and a detector. Designated FERET sytem, (Field Energy Recoid Emission Technology), it would detect substances identi ...

Polymer Bridge Systems, with over 8 years of research composite bridges, found that success hinges on being dollar-for-dollar cost competitive with steel and concrete. We founded the four "golden rules" that are required: the bridge must be: 1) factory build; 2) road transportable; 3) installed in 1 eight-hour day; and 4) be cost-competitive on an installed cost basis. This bridge will be buil ...

Halobutyl rubber is used as an inner liner for tubeless automotive tires because of its low permeability to gases and good compatibility with other tire materials. However, at high pressures and over prolonged time periods, tires leak. Factors such as under-inflation and heat are major contributors to tire damage. While the tires are slowly losing air pressure, consumers also do not maintain c ...

This proposal is to investigate a concept of a shock producing component that will be the basis of a machine to remove deteriorated concrete pavement. The principal has been proven feasible, but further demonstration has to be accomplished to proceed with application and expense of continued development of a Road Remover/Recycler. This machine will move continuously on a lane width of pavement a ...
