Application of Fracture Mechanics in the Design of Low-Alloy Steel Cast- ings for Heavy Mobile Equipment (17-035) Patrick Severson, Rani El-Hajjar, Pradeep Rohatgi, University of Wiscon- sin-Milwaukee (Milwaukee); Hathibela- gal Roshan, Maynard Steel Casting Co. (Milwaukee) Low-alloy steel castings are im-
portant components in structures for heavy mobile equipment. Typically, cast components are analyzed by de- termining the mean stress, stress range and von Mises stress. Using these stresses, an engineer can determine fatigue life using the Modifi ed Good- man approach, along with determining adequate safety factors for strength and fatigue. Fracture mechanics prop- erties of a typical low-alloy steel and its application in the design of castings will be discussed.
Invention of Variable Density Lightweight Steel Castings for Army, Naval and Civilian Applications (17-036) Hathibelagal Roshan, Maynard Steel Casting Co. (Milwaukee) T e ability to absorb energy of
impact or blast is crucial to the design of army and navy structures. Metal- lic foams possess low density, energy absorption and vibration damping ca- pabilities. At Maynard Steel, inventive developments of steel foam have been made that result in lower weight com- pared to solid steel. U.S. and interna- tional patent applications are pending for these developments. T e intent of this presentation is to bring awareness to defense and civilian engineers and designers regarding the availability of this new material for applications.
8-11:30 a.m. AFS Institute Course: Virtual Cast- ing Process Dave Charbauski, Consultant (Sugar Grove, Illinois) T is course will provide a basic
overview of the metalcasting process. Mar/Apr 2017 | METAL CASTING DESIGN & PURCHASING | 41
It will trace the path of a casting from quoting through shipping.
9:15-10:15 a.m. Development and Casting of High Cerium Content Aluminum Alloys (17-013) David Weiss, Eck Industries, Inc. (Mani- towoc, Wisconsin) This session will describe the
development and castability of near eutectic aluminum-cerium alloy systems. The castability ranking of the binary systems is as good as or better than the aluminum-silicon system with some deterioration as additional alloying elements are added. Production systems for melt- ing, de-gassing and other processing of aluminum-silicon or aluminum- copper alloys can be used without modification for conventional cast- ing of aluminum-cerium alloys.
Honorary Lecture: Survival in a Brave New World of Metalcasting (17-132) Kyle Metzloff , University of Wisconsin- Platteville (Platteville, Wisconsin) Will your foundry be around in
20 years? What is the difference between a growing and dying found- ry? What are the common themes in people, processes, technological innovation and adaptation that are keeping the top foundries relevant?
11:30 a.m.
Division Recognition Luncheon T is luncheon will feature the
presentation of the Best Paper and Division awards, as well as the Applied Research and Howard F. Taylor Awrd. (Ticket required.)
