CAREER: Plastic Flow in Reinforced Metals Subjected to Multiaxial Loading

该项目的总体目标是启动一个强大的学术生涯整合材料力学领域的教育和研究活动。 该研究项目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。 将对增强铝进行研究，以提供与金属基体中的约束塑性流动相关的整体塑性的多轴描述。 恒定的塑性流动的轮廓将实验确定的内部压力轴向扭转加载的增强管试样，然后利用，在细观力学的帮助下，开发一个宏观尺度的连续模型。 主要的教育目标是在一个更具参与性的环境中向学生介绍力学问题，即学生体验力学而不是被动地学习力学。主要的教育活动是通过研究真实的制造产品和结构元件，开发强调力学理论，数值计算和实验一体化的本科课程。

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.
