CAREER: Plastic Flow in Reinforced Metals Subjected to Multiaxial Loading

该项目的总体目标是在材料力学领域开创一个强大的学术生涯，将教育和研究活动结合起来。研究计划的目的是全面了解增强金属（特别是颗粒增强和纤维增强铝）在多轴载荷下的塑性响应。对增强铝的研究将进行，以提供与金属基体中受限塑性流动相关的整体塑性的多轴描述。通过实验确定了增强管试件内压-轴扭加载下的恒定塑性流动轮廓，并结合细观力学建立了宏观尺度连续体模型。主要的教育目标是在一个更具参与性的环境中向学生呈现力学问题，也就是说，学生可以体验力学而不是被动地学习力学。主要的教育活动是发展本科课程，强调通过研究实际制造产品和结构元件将力学理论、数值计算和实验相结合。

The overall goal of this project is to initiate a strong academic career integrating educational and research activities in the area of mechanics of materials. The objective of the research program is to develop a comprehensive understanding of the plastic response of reinforced metals (especially particulate-reinforced and fiber-reinforced aluminum) subjected to multiaxial loading. A study of reinforced aluminum will be performed to provide a multiaxial description of overall plasticity associated with constrained plastic flow in the metallic matrix. Contours of constant plastic flow will be experimentally determined for internal pressure-axial-torsional loading of reinforced tubular specimens, then utilized, with the help of micromechanics, to develop a macroscale continuum model. The primary educational goal is to present mechanics issues to students in a more participatory environment, that is, one in which the students experience mechanics rather than passively learn about it. The primary educational activity is the development of an undergraduate course that emphasizes the integration of mechanics theory, numerical computations, and experiments through study of real manufactured products and structural elements.
