Polydicyclopentadiene (PDCPD) is a polymer material which is formed through ring-opening metathesis polymerization [2] (ROMP) of dicyclopentadiene (DCPD). PDCPD exhibits high crosslinking, which grants its properties, such as high impact resistance, good chemical corrosion resistance, and high heat deflection temperature.
The structural analysis and design software CSI produce include SAP2000, CSiBridge, ETABS, SAFE, PERFORM-3D, and CSiCOL. One of Computer and Structure, Inc.'s software, ETABS, was used to create the mathematical model of the Burj Khalifa , currently the world's tallest building, designed by Chicago, Illinois –based Skidmore, Owings & Merrill ...
With the emergence of the Internet, the capability of MDBs increased. Web-enabled MDBs provide a more centralized management and conservation of Materials data. Finding and accessing the required data is faster than to search for them in a traditional manner, e.g. from handbooks or Microsoft Excel files.
This permitted the use of a centralized data storage, improving the maintenance of data. From a technical point of view, therefore, a database was necessary. [22] In 1976 SAP GmbH Systeme, Anwendungen und Produkte in der Datenverarbeitung ("Systems, Applications, and Products in Data Processing") was founded as a sales and support subsidiary.
A UNS number only defines a specific chemical composition, it does not provided full material specification. Requirements such as material properties (yield strength, ultimate strength, hardness, etc.), heat treatment, form (rolled, cast, forged, flanges, tubes, bars, etc.), purpose (high temperature, boilers and pressure vessels, etc.) and testing methods are all specified in the material or ...
One project that has looked at this issue in-depth is the Material Data Management Consortium (MDMC), [1] a collaboration of leading aerospace, defense, and energy enterprises - organizations such as NASA, Boeing, Rolls-Royce plc, Honeywell, and GE Aviation. The MDMC has identified the problems caused by failures in the materials data ...
C17200 beryllium copper alloy has strength and hardness similar to that of steel; Rockwell hardness properties in its peaked age condition [further explanation needed] are in the range of 200 ksi and RC45. C17200 has effective corrosion-resistant properties when exposed to harsh conditions such as seawater, and down-hole environments.
The pyroelectric and ferroelectric properties of barium titanate are used in some types of uncooled sensors for thermal cameras. Barium titanate is widely used in thermistors and positive temperature coefficient heating elements. For these applications, barium titanate is manufactured with dopants to give the material semiconductor properties ...
