Elastomer wear conference held.The University of Wisconsin-Milwaukee will hold a seminar on "Fatigue and wear of elastomers," May 10-12 at the UWM UWM University of Wisconsin - Milwaukee UWM University of Wisconsin - Madison UWM Universal Window Manager UWM Unweighted Mean UWM Unix Window Manager UWM Ultimate Window Manager School of Continuing Education The School of Continuing Education is a part of the North Orange County Community College District, located in northern Orange County, California. The School of Continuing Education provides non-credit continuing adult education, English as a Second Language, vocational skills, in downtown Milwaukee, WI. Overall, this course will review the fundamental factors underlying the fatigue and wear of elastomers. This will include such varied factors as the influence of thermo-mechano-chemical environments (i.e., monotone mon·o·tone n. 1. A succession of sounds or words uttered in a single tone of voice. 2. Music a. A single tone repeated with different words or time values, especially in a rendering of a liturgical text. , cyclic and mixed histories-mission profiles); varying loading-slip directionality; the full spectrum of rate effects, including creep-relaxation, slow, very rapid and shock rates of loading; material-component processing effects (i.e., polymerization polymerization Any process in which monomers combine chemically to produce a polymer. The monomer molecules—which in the polymer usually number from at least 100 to many thousands—may or may not all be the same. scheme, mixing type, extrusion, molding); material morphology; and aging. All these various factors will be incorporated in the fatigue and wear life estimates models. These will be developed into both empirical representations, as well as analytical-numerical (FEA (Finite Element Analysis) A mathematical technique for analyzing stress, which breaks down a physical structure into substructures called "finite elements." The finite elements and their interrelationships are converted into equation form and solved mathematically. ) applications models. Dr. Joseph P. Padovan, a professor of mechanical and polymer engineering in the Colleges of Engineering and Polymer Science Polymer science or macromolecular science is the subfield of materials science concerned with polymers, primarily synthetic polymers such as plastics. The field of polymer science includes researchers in multiple disciplines including chemistry, physics, and engineering. and Engineering at the University of Akron Enrollment in fall 2006 was 23,539 students.[1] The school offers more than 200 undergraduate degrees [2] and 100 graduate degrees [3]. The University's best-known program is its College of Polymer Science and Polymer Engineering, which is located in a , OH, will be the course instructor. An introduction to factors underlying fatigue and wear will examine material properties, fracture basis of events, processing effects, rate effects and thermo-mechano-chemical-environmental issues. Quasi static and dynamic mechanical and strength properties of elastomers will be explored, including very slow, slow, medium and high shock rate effects on mechanical response properties, creep-relaxation properties, and rate effects on rubber and strength characteristics. Fatigue of elastomeric components will be discussed, including an overview and presentations on the role of material morphology (hierarchy of morphologies, initiation of fracture, role of crack tip behavior and causes of crack branching), processing effects on fracture properties (type of polymerization, i.e., emulsion versus solution, mixing effects, mixed processing events, potential material anisotropy anisotropy /an·isot·ro·py/ (an?i-sot´rah-pe) the quality of being anisotropic. anisotropy (an´āsôt´r ), environmental factors (monotone, cyclic, mixed events, including mechanical, thermal loading, chemical environments and mixed mission profiles), crack growth properties and life estimate modeling methods. Discussions on wear will include an overview, some fundamental characteristics, role of material morphology, role of processing effects, straight versus mixed directional wear, thermo-mechano-chemical effects, and empirical and analytical-numerical (FEA) formulation of wear models. The course fee is $1,090. Further information is available from Murali Vedula (414) 227-3121. |
