Nonlinearity Parameters Of Polymers, Meng-Chou Wu
Nonlinearity Parameters Of Polymers, Meng-Chou Wu
Dissertations, Theses, and Masters Projects
Three types of acoustic nonlinearity parameters for solids are discussed. The results of measurements of these parameters for three polymers--polymethyl methacrylate, Polystyrene, and polysulfone--are presented.;The author has developed a new technique, using piezoelectric transducers directly bonded to the specimens, which allows the measurements of fundamental and second harmonics generated in the solids, and thereby the determination of nonlinearity parameter {dollar}\beta\sb3{dollar}, which is the ratio of a linear combination of second- and third-order elastic coefficients to the second-order elastic coefficient.;The second nonlinearity parameter, B/A can be determined from the temperature and pressure derivatives of the sound velocity. We derive its exact …
Relationships Between Chemistry Variations And The Morphology And Nodular Formation Of Carbon Nodules In Ductile Cast Iron, Donald Francis Cassel
Relationships Between Chemistry Variations And The Morphology And Nodular Formation Of Carbon Nodules In Ductile Cast Iron, Donald Francis Cassel
Dissertations and Theses @ UNI
The purpose of this study was to determine what relationships exist between the chemistry and the morphology and nodular formation of carbon nodules in commercially produced ductile cast iron. Additionally, the effects of chemistry on the hardness of produced castings from net shake processes were investigated. According to pertinent information in current literature, the hardness of castings has a direct bearing on the final cost of products.
The method of gathering this information and developing a correlation between the chemistry variations and the morphology and nodular formation was facilitated by the cooperation of a commercial producer of ductile cast iron …
