论文摘要
模拟工具在材料科学和工程中起着越来越重要的作用,超出了其在研发中的重要重要性,这些工具具有巨大的教学潜力。我们描述了一组在线模拟工具和学习模块,旨在帮助学生探索材料科学中的重要概念,在这些材料科学中,具有高保真模拟的动手活动可以提供洞察力,否则不容易获得。涉及密度功能理论和分子动力学模拟的在线工具已经考虑了非专家最终用户的设计,只需要几下单击即可执行大多数模拟,但是它们由研究级代码提供动力,专家用户可以访问高级选项。所有工具和模块均可在Nanohub.org中在线模拟,并且访问是免费的,并且免费。重要的是,讲师和学生无需下载或安装任何软件。学习模块涵盖了从晶体和掺杂的电子结构,金属中的塑性变形以及聚合物的物理特性的一系列主题。这些模块已在普渡大学材料工程学院的几个核心本科课程中使用,它们是自给自足的,很容易纳入现有课程。
Simulation tools are playing an increasingly important role in materials science and engineering and beyond their well established importance in research and development, these tools have a significant pedagogical potential. We describe a set of online simulation tools and learning modules designed to help students explore important concepts in materials science where hands-on activities with high-fidelity simulations can provide insight not easily acquired otherwise. The online tools, which involve density functional theory and molecular dynamics simulations, have been designed with non-expert end-users in mind and only a few clicks are required to perform most simulations, yet they are powered by research-grade codes and expert users can access advanced options. All tools and modules are available for online simulation in nanoHUB.org and access is open and free of charge. Importantly, instructors and students do not need to download or install any software. The learning modules cover a range of topics from electronic structure of crystals and doping, plastic deformation in metals, and physical properties of polymers. These modules have been used in several core undergraduate courses at Purdue's School of Materials Engineering, they are self contained, and are easy to incorporate into existing classes.
