材料力学是一门工科类专业的重要的基础必修课程。通过对本课程的学习,使学生对杆件的强度、刚度和稳定性问题具有
明确的基本概念、必要的基础知识、较熟练的计算能力以及一定的分析能力和初步的实验能力。培养学生的力学素质和定
性定量分析能力,为学生学习相关专业课程及进行结构设计和科学研究奠定良好的基础。
材料力学教学要强化力学的基本概念和基础理论的教学;强调与工程背景的密切结合。
课程的主要内容包括:杆件的内力分析、应力分析、应力状态分析、位移分析、强度分析与设计、刚度分析与设计、压杆
的稳定性分析与设计、能量原理与应用、疲劳失效分析与设计、复合材料的力学行为等。
Mechanics of materials is an important basic compulsory course for engineering majors. Through the study of this
course, the students will understand the basic concepts and knowledge of the strength, stiffness and stability problems of
rob, and therefore obtain explicit calculation ability, skilled analysis ability and experimental ability. The course is intended
to train students' mechanical quality and qualitative and quantitative analysis ability, laying a good foundation for students
to study related courses and structure design and scientific research.
The teaching of material mechanics should strengthen the teaching of the basic concepts and the basic theory of
mechanics, and emphasize the close combination with engineering background.
The main contents include: bar internal force analysis, stress analysis, stress analysis, displacement analysis, strength
analysis and design, stiffness analysis and design, column stability analysis and design, energy method and application,
fatigue failure analysis and design, mechanical behaviour of composite materials.
