摘要
文章针对莫尔圆图解粉体层单元体斜截面上的应力状态时,初学者易混淆的点与面、夹角之间的对应关系进行了辨析;梳理了莫尔圆在描述粉体压缩流动及料仓设计等工程实际中的应用。在教学过程中,采用探究学习式进行相应实验巩固所学理论,培养学生的学习能力。
The paper discriminated the relationship of the point on Molar＇s circle and the oblique plane of powder element, and the angles between them which confuse beginners when using Molar＇s circle to map stress condition on the plane, The application of Mohr＇s circle to describe the compression flow of powder and to guide the design of silo in project practice were sorted out. In the course of teaching inquiry learning was adopted to consolidate further the students＇ knowledge of the theory and to foster students＇ learning abilities through offering of the corresponding experiment.
