2006-608: MEMORY METALSJohn Marshall, University of Southern Maine Page 11.922.1© American Society for Engineering Education, 2006 Memory MetalsThere are two very common ways to create motion from electricity - motors andsolenoids. Most of the equipment and machines found in homes, factories and officestoday make extensive use of these two devices. Both motors and solenoids rely onmagnetic fields to produce the mechanical motion that is utilized for linear and rotarypower transmission.Due to recent advancements in memory metals, another method of creating motion hasbecome available that does not rely on magnetic fields. Memory metals are specialmetals
valves cannot keep pace with the commands ofthe computerized controllers.MR fluid, can “cycle” at a rate of 200 times per second. As a result, this technology willallow devices that can operate instantly and without mechanical valves. Increasedproductivity and better product quality through more dependable and responsiveautomated equipment is just a small part of what this maturing technology can deliver.The presentation will be followed by an actual demonstration of the materialexperiment and an opportunity for participants to actively engage this extraordinarysubstance.Student ActivityThis activity will be useful to students studying material technology as well as thoseinvolved in industrial power transmission, automation, and process control
can serve as a basis for amore advanced investigation into magnetism and materials. Those students who haveinsight into industrial power transmission systems (electrical, mechanical, hydraulic, andpneumatic) and process control technologies (programmable logic controllers, etc.) willsee the enormous advantages this technology has to offer over traditional methods.Outcomes and Post-Lab AnalysisA suggested post-lab analysis would be to contrast response times and “mean timesbetween failures” from a traditional power and control system, to one that utilizesmagneto-rheological fluids.Even though hydraulics has the highest power to weight ratio of any industrial powertransmission system, the mechanical servo valves and directional controls valves

fit for an active learning redesign, as several of the keyconcepts introduced in an undergraduate materials class can be explored using hands-onactivities, and exposure to such actives enhances student engagement and understanding [4]. Thebenefits of a lab component in an introductory materials course have been observed directly atUSC, as the aerospace engineering version of the class (AME 231L: Mechanical Behavior ofMaterials) incorporates a materials testing lab. AME 231L is a smaller course, capped at 30students, and taught once per year. The small class size, and the availability of lab space andequipment, enable a hands-on learning experience for students. Anecdotal evidence frominstructors suggest that students in AME 231L develop a

The creation of a demonstration kit called “What’s in the Box?” has allowed for directapplication of “Room with A VUE” in the laboratory along with the lecture hall. Students arerequired to purchase a kit containing common objects ranging from mechanical pencils to paperclips (Accessible) – see Figure 4. Presently the kits have 7 formalized experiments.

concerning the atomicmechanisms of plastic deformation within the context of a laboratory exercise. Sophomorematerials engineering students performed, analyzed, and compared results from both a traditionaltensile test of metals and a molecular dynamics simulation tensile test of a nanowire. The latterwas performed using the Nano-Materials Simulation Toolkit on nanoHUB.org. Students’responses to in-lab worksheet questions, their written lab reports, and their responses to a relatedexam question were qualitatively analyzed. Recommendations are made for better integration ofthe simulation and traditional tensile test components of the lab.IntroductionThe atomic mechanism of plastic deformation of metals is a difficult concept1,2.

priority at that time,however, demanded integration of engineering science content to align the curriculum with theABET standards).The analytical content requiring math knowledge in such courses was adjusted to encourageparticipation and learning by the entire class. Additionally, our program’s distinctly vocationalfocus required that the ‘structure’ component of the central paradigm of materials science:process structure properties performance, be given reduced emphasisii. This posed achallenge because understanding and visualizing how microstructure design via processinginfluences material behavior lays the foundation for understanding, analyzing, predicting andcontrolling the performance of larger, real systems.

Session 1664 Session 1664 Introducing Statistics to Mechanical Engineers in a Materials Science Course Scott R. Short, Ph.D., P.E. Northern Illinois UniversityMany schools are reducing the number of credit hours in undergraduate engineering programs sostudents have a better chance of graduating in four years. However, a majority of engineeringeducators feel that certain fundamental engineering topics such as materials engineering andstatistics should be
in the lecture course, generally the “Introductionto Materials Science and Engineering”. A survey of university department syllabi found themajority of sophomore laboratories at these universities to be focused on a few techniques andtools, mainly related to mechanical behavior of materials. In the survey undertaken, no universitymaterial science departments were found to offer a course related to sustainable materials.Within the MSE Department at UF, laboratories are central to the MSE student experience. Aspart of an ongoing redesign of curriculum within the department, in 2013 the Junior Laboratorycourses were redesigned to support the core content courses that all MSE students take in theirjunior year. Additionally, the laboratory

In addition, it has been used for smallsections of general chemistry in a liberal arts college and large sections of organic chemistry at acomprehensive university.

Properties of Materials." The one prerequisite is one class inCollege Chemistry. The course is required by students in Industrial, Mechanical, and MaterialsEngineering programs. Normally it is taken in freshman or sophomore year, but since about halfof the engineering students are transfers, so there are also many juniors and seniors in the class.The class demography was as follows. The 38 students included: Aerospace Engineering (3sophomores and 1 senior); Bioengineering (2 seniors); Chemical Engineering (4 juniors and 2seniors); Industrial Engineering (3 juniors and 1 senior); Mechanical Engineering (8 sophomores,7 juniors, 4 seniors, and 1 graduate student); 1 sophomore business major, and 1 junior Spanishmajor.
