Integrating Fatigue Analysis into a Machine Design Course or Finite Element Course Josh Coffman, Sachin S. Terdalkar, Joseph J. Rencis/Ashland O. Brown University of Arkansas, Fayetteville/University of the PacificAbstractFatigue is a major topic addressed in undergraduate and graduate machine design courses.Practicing engineers today commonly solve fatigue problems by hand coupled with static finiteelement analysis. More recently fatigue modules have been incorporated into a few commercialfinite element codes which are emerging as a powerful numerical tool.

someone make such aninvestment? What are the motivating factors? Of course, there are the enticements of highsalaries and prestige. But with lower percentages of American students currently choosingscience and engineering than in other major nations of the world, maybe it‟s time to rethink theadequacy of such motivations. A recent New York Times editorial by Columbia Universityphysicist and Author, Brian Greene, strongly advocates teaching science in a way that includesits dramatic implications for worldview. He emphasized “the powerful role science can play ingiving life context and meaning”. He suggested that instead of just focusing on the technicaldetails, “science needs to be taught to the young and communicated to the mature in a mannerthat

72000). Trust is defined by Avolio et al., (2000) quoting (Mayer, Davis, & Schoorman , 1995, p.712) as “the willingness of a team member to be vulnerable to the actions of other teammember(s) based on the expectation that the other(s) will perform a particular action important tothe trustor, irrespective of the ability to monitor or control other team member(s).”Trust is critical in virtual work since direct supervision, similarity in backgrounds, andexperience and a common form of social control in traditional workforce are not feasible. Hence,leadership in virtual workforce should facilitate the formation of trust building in a virtualworkforce context. As a result, the effects of leadership on trust should not be underestimated.Since

Thefollowing universities are included: University of Oklahoma (OU), Oklahoma State University(OSU), University of Colorado at Boulder (UC), and University of Texas at Austin (UT).Selection of these schools s based on several factors, including program size (faculty and studentpopulation), funding source (public vs private) and geographic location. Among the fouruniversities selected, UT is the largest based on the faculty and student size, followed by UC.The other two schools (OU and OSU) are of similar size and representative of typical programsacross the country. All the selected schools are public institutions. Data for this

source.Magnetic Nano-Particles Lab (1) The purpose of this lab is to show students how to make nano-particles using homogenousnucleation. When ferrofluids were first developed at NASA in the 1960’s, magnetite particles werereduced to the nano-scale through a long milling process. In this lab students learn the advantages ofsynthesizing magnetite particles on the nano-scale using a bottom-up approach. The magnetic nano-particles will also be used in Functionalization and Nano-composite labs. The first process is tomeasure 25 mL of HCl solution into one beaker and 100 mL of HCl solution into the second. Then,measure out 1 g of Iron (II) Ferrous Chloride, and add this powder to the 25 mL of HCL in the fumehood. The yellow solution can be seen in

DiscussionFigure 4 shows a plot of temperature (K) as a function of time (s) for the black (painted) surfaceplaced normal to the sun (θ = 0°). Both the experimental data from Table 1 and the predictedtemperatures from the model development and the solar flux which causes the model to best fitthe experimental data (750 W/m2) are presented. Similar plots were obtained for the blacksurface placed at angles of 45° and 60°, and for the unpainted aluminum surface placed normalto the sun. This good correlation between experimental data and the model correlation indicatesthat the assumptions made about convection leaving the plate were valid.

Butcher claims the reports call for “ingenious leaders —ingenious engineers” and calls these engineers, “well-rounded RenaissanceEngineer”[s] [8]. Turns, Atman, et al., [9] use these reports as an input to what anengineer needs to know. Dym, et al. present how engineering education is beingchallenged to require students to consider additional design constraints required aspart of a “new fundamentals” [10]. In response to this challenge, the CoE at WSUwishes to establish its leadership in reshaping the undergraduate experience toprepare the engineer of 2020, and at the same time make the educationalexperience more meaningful to the

Our experience has shown that careful recreation of student claimed results andrequiring detailed design reports to be submitted can allow for a successful course. The amountof interaction required with distance students and remote submission of designs is increased andcan require significant time on the part of the course instructor or TA if a large number ofdistance students are enrolled.References[1] Forger, G., Reynaert, J. and Penfield, S., “An Online Language Lab: Reaching and Teachingat a Distance.

The SEM analysis proved that the average diameters ofnanocomposite fibers were increased from 700 nm to 1.6 µm by increasing the CNTconcentrations. This demonstration improves the knowledge of the students on how to design,analyze and manufacture nanomaterials and devices using electrospinning method.REFERENCES1.
