材料力学内力图的统一画法

A Unified Drawing Method of Internal Force Diagram of Material Mechanics

利用数学中的导数和定积分等知识对材料力学的轴力图、扭矩图、剪力图和弯矩图形成统一的画法,运用这种方法画内力图速度快、效率高、准确性高,体现了材料力学课程的关联性,而且为材料力学模块化教学提供了思路。教学实践证明,该方法简单明了、好学易懂、学生易于掌握,对今后的教学和工程实际具有一定的指导意义。

This paper form a unified drawing method for axial force diagram, torque diagram, shear diagram and bending moment diagram by using mathematical derivative and definite integral, it is fast. high efficiency and high accuracy to draw internal force diagram by using the method, and embody relevance of material mechanics, also provide thought for modular teaching of material mechanics. Teaching practice revealed that it has the characteristic of simpleness and cleaness, easiness to understand, and it is convenient for student to comprehend, also has certain directive significance for teaching and engineering practiceo
