Engineering - Mechanical (56)Polymers and polymer-based composites are rapidly replacing metals as the material of choice in many engineering applications and characterizing the behavior of polymeric materials demands concepts and tools that are different from those that describe the response of metals. In contrast, the fundamental strength of materials course on most campuses has remained unchanged for decades. Through this project, the mechanics of materials course is being transformed to include modern topics and new pedagogies. The focus of the course is on the fundamental behavior of materials in terms of loading and failure with attention to the general case of non-linear materials and their practical applications. Linear materials response, which constitutes the traditional educational approach to mechanics of materials instruction, is included in the course as a specific case that extends from the general case. The course is being taught using a problem-based-learning approach with seven challenges selected to highlight both traditional and modern materials as well as linear and non-linear behavior. Student learning through this new approach is being rigorously assessed and compared to learning through traditional courses.

在许多工程应用中，聚合物和聚合物基复合材料正在迅速取代金属作为首选材料，表征聚合物材料的行为需要不同于描述金属反应的概念和工具。相比之下，在大多数校园里，材料课程的基本力量几十年来一直没有改变。通过这个项目，材料课程的机制正在转变为包含现代主题和新的教学方法。本课程的重点是材料在加载和破坏方面的基本行为，并关注非线性材料的一般情况及其实际应用。线性材料反应是构成材料力学教学的传统教育方法，是作为一般案例延伸的具体案例纳入课程的。该课程采用基于问题的学习方法进行教学，其中选择了七个挑战，以突出传统和现代材料以及线性和非线性行为。通过这种新方法学习的学生正在被严格评估，并与通过传统课程学习的学生进行比较。
