Sun. June 26, 2016 9:00 AM to 12:00 PM
Room 262, New Orleans Convention Center
Session Description

Ticketed event: $20.00
It is important that engineering and science students be introduced to the idea of modeling and the use of simulation tools. Models are at the heart of engineering problem-solving, and simulations not only help students understand complex phenomena but also play important roles in research and industry. Computational tools are used to gain insight into the behavior of systems and to shorten the development cycle for new products. High-power computing resources and increasingly sophisticated computational methods now enable simulations that can realistically describe the behavior of many materials, processes and devices [1]. The increasing importance of computational simulations for materials engineering is reflected in the national Materials Genome Initiative (MGI) [2, 3] and recent report on Integrated Computational Materials Engineering (ICME) [4]. Future engineers will likely be required to use advanced simulations to solve many of tomorrow's challenges.

In this workshop, an overview of the wide range of materials simulation tools, learning activities and courses that are available on nanoHUB will be presented, and hands-on activities will focus on using a set of simulation tools that is appropriate for use in introductory materials courses. These tools provide elegant representations of materials that enable students to see and interact with atomic-level structures and processes that are responsible for the behavior of materials. For example, simulations show how macroscopic plastic deformation in metals results from motion of atoms at the nanometer scale. Many other materials concepts can be illustrated through nanoHUB simulations, including Miller planes in a variety of crystal structures, dislocation formation and movement, the role of critical resolved shear stress, the ductile to brittle transformation, atomic behavior during crack propagation and thermal expansion. This workshop will demonstrate how simulations can be integrated into course topics such as tensile testing of materials, thermal response, phase change, and plastic versus brittle failure.

The workshop will provide some background on Molecular Dynamics (MD) simulations, including a perspective on where MD simulations lie in the modelling and simulation landscape, what its strengths for education are, and guidance on the limitations of this technique. A Framework for Effective Use of Research-Grade Simulations in the classroom [6] will also be presented and utilized in the workshop’s activities.

Through the course of the workshop, participants will work on an assignment to assemble a personal collection of material in their own nanoHUB space that includes specific simulation tools, activities and other resources that they can take away and use in their own courses. As instructors personalize and develop their own activities around simulation tools, they can share these materials through collections or formal nanoHUB publications. The workshop will be conducted utilizing a nanoHUB group, wherein the participants and instructors can communicate and collaborate after the conclusion of the workshop, providing one another with ongoing support.

Each participant is encouraged to bring a laptop computer or tablet with wireless internet connectivity and create a free nanoHUB.org account before the workshop in order to fully take part in the hands-on activities.

Speakers
  1. Dr. Tanya Faltens

    Purdue University, West Lafayette (College of Engineering)

    Dr. Tanya Faltens is the Educational Content Creation Manager for the Network for Computational Nanotechnology (NCN), and NSF-Funded project that created the open access nanoHUB.org cyber-platform. Her technical background is in Materials Science and Engineering (Ph.D. UCLA 2002), and she has several years’ experience in hands-on informal science education, including working at the Lawrence Hall of Science at UC Berkeley. While at Cal Poly Pomona, she taught the first year engineering course, mentored undergraduate capstone research projects, and introduced nanoHUB simulation tools into the undergraduate curriculum in materials science and engineering and electrical engineering courses. Much of her work has focused on introducing STEM concepts to broad audiences and encouraging students, including women and others in traditionally under-represented groups, to consider graduate school.

    Some of Dr. Faltens' current projects include investigating the value added to education by incorporating simulations, creating pathways to introduce a diverse range of students to research opportunities that involve computational simulations, connecting with teaching faculty to share ideas on how nanoHUB simulations and other educational resources can be used in their courses, and growing the Materials Science community on nanoHUB www.nanohub.org/groups/materials.
