摘　　要：针对塑性力学课程中屈服准则的复杂性和抽象性,设计了一项关于各向异性金属材料屈服面测定的研究性实验。采用“理论教学+实验教学+互动研讨”的教学模式,旨在培养学生独立运用塑性力学理论知识解决实际问题的能力,激发学生的创新思维。教学实践表明:该研究性实验教学策略的实施促进了学生对塑性力学课程中公式、概念及理论要点的深入理解,解决了塑性力学理论知识晦涩难懂的问题;促进了学生分析问题、解决问题能力的培养,增强了学生的团队协作能力和科研素养,弥补了塑性力学理论教学中的不足,提升了塑性力学课程的教学质量和效果。ness of the yield criterion in the course of plastic mechanics,a research experiment on the measurement of the yield surface of anisotropic metal materials is designed.In order to expand students’understanding of the yield criterion and the yield evolution of anisotropic materials,and focus on the yield behavior of magnesium alloys with significant anisotropy,the teaching mode of“theoretical teaching+experimental teaching+interactive discussion”is adopted to cultivate students’ability to independently apply theoretical knowledge of plastic mechanics to solve practical problems,and stimulate students’innovative thinking.The teaching practice shows that the implementation of this research experiment teaching strategy greatly promotes the students’deep understanding of the formulas,concepts and theoretical points in the course of plastic mechanics,and effectively solves the difficult problems in the study of theoretical knowledge of plastic mechanics.In addition,it improves students’ability to analyze and solve problems,enhances students’teamwork ability and scientific research accomplishment,makes up for the deficiencies in the teaching of plastic mechanics theory,and comprehensively improves the teaching quality and effect of plastic mechanics course.
