Session 3264 Failure Analysis – A Technology Enhanced Capstone Experience for Materials Engineers David Gibbs, Alan Demmons, Robert Heidersbach Ph.D., Daniel Walsh, Ph.D., College of Engineering Cal Poly, San Luis ObispoAbstract:The evolution of a highly successful curricular experiment is documented. This unique course is an ancestor to manyof the “mechanical dissection” approaches to engineering education which are so very popular today. The paperhighlights the value of the course as a culminating experience for the materials
design their very own newgreen materials and perform life cycle assessments of these materials. Students work together asa group to perform all the steps of the project from design to manufacturing and testing. Inalignment with Constructivist Learning Theory,11 students work in groups, and engage in groupdiscussion to predict the mechanical behavior of their “Greencrete” based on the type andpercentage of the recycled material used. Each group is required to propose a real application fortheir Greencrete, which could be load bearing or non-load bearing, based on the predictedmechanical behavior. Each group is required to build a laboratory scale sample and designexperiments. Students also have the opportunity to improve their written and
misconceptions. These factors include (1) the unfamiliarityof the relevant education literature to many engineering educators, (2) the lack of concept inventories withgood estimates of internal consistency and validity that address core engineering areas and (3) the lack oftested educational materials in engineering similar to those that have been developed and tested inphysics. However, significant progress is happening related to each of these issues. There is awidespread and rapidly growing awareness of the benefits of active-engagement methods in engineeringeducation (Prince, 2004) and significant progress has been made in developing concept inventories forcore engineering topics (Evans, 2003; Reed-Rhoads and Imbrie, 2007; Streveler et al., 2008

It is expectedthat these student-built analogies will add to the learning effectiveness. In addition, this maylead to additional analogies and demonstrations being incorporated into the class discussion.ConclusionThe authors have used the teaching aids presented in this paper as an effective method ofexplaining and demonstrating difficult topics in materials engineering.

perfectly with theincreasingly computational field of materials science and engineering. Atomistic computationalmodeling techniques are “one-to-many” [36], meaning that one modeling technique can addressmany MSE phenomena. This is because atomistic techniques are based on fairly basic atomicbehavior from which larger-scale properties emerge. One-to-many models have advantages bothscientifically and educationally. Scientifically, they enable the modeling of real complexmaterials without needing to make overly simplistic modeling assumptions. Educationally, theyhelp students grasp the underlying mechanisms of MSE phenomena and connect them with morebasic physical principles.Rather than being seen as advanced topics, computational techniques should be

Futureiterations of this approach could include an optimization of the process parameters that havebeen kept constant, such as print infill geometry and print infill density. To date, studentshave worked with off-the-shelf filaments. Additional access to a filament extrusion systemwould allow students to synthesize new candidate materials (with new fiber volumefractions) proposed by the ML model. After printing, mechanical properties (such as tensilestrength and modulus), thermal properties (such as glass transition temperature) and physicalproperties (density

Reinforcement of Technical Learning The use of models improves the learning process of civil engineering students by reinforcing their previous knowledge. According to the results experimented by some students, “it was possible to review the optimal level of compaction (Standard Proctor Test) that was learned in Soil Mechanics” (Group 8). The students had to use knowledge from previous classes to make their projects function correctly, as “skills from the Pavement Design class were recalled in order to work with the emulsion properly” (Group 7).

Thislab typically taken during the third academic year is 3-credits due to the heighten emphasis ontechnical report writing. Students are introduced to technical writing, data acquisitions, anduncertainty/error analysis. Like the prior lab, students complete six guided experiments focusedon the following areas: mechanical property of materials, vibration, stress analysis and strengthof materials. Additionally, the students are expected to design a simple experiment to verify amechanical response. Labs are performed in teams of three or four students.

Asindicated by the comments below, students noted that obtaining high grades are a mechanism forattaining high quality, post-graduation academic and career opportunities. “I won’t deny that having high grades feels good. It has been positively reinforced since I was a child, and it gives you a sense of security for getting a job, internship, etc.” “Exuberant. It means that I am making good steps
ResearchIntroductionPracticing mechanical engineers interface with machinists to design and manufacturecomponents in metal and other engineered materials. Direct, hands-on exposure to precisionmachining operations, like mill and lathe work, helps engineering students designmanufacturable components and graduate as professionals who are better able to collaborate withmachinists, operators, and other members of a manufacturing team [1]. Although the benefit ofdirect experience with machining is indisputable, programs struggle to implement “shop”experiences with fidelity for a variety of reasons, including: (1) constraints on equipment,staffing, and material resources, particularly for large-enrollment classes; (2) long gaps in thecurriculum between machining experiences
