摘　　要：介绍了一种关于材料力学中轴力、扭矩、剪力和弯矩等内力图的直接画法,建立了内力的增减与外力方向之间的关系.该方法在实际教学过程中为广大学生所接受,取得了良好的教学效果.A direct drawing method of internal force diagram such as axial forces, torsions, shear forces and bending moments in Material Mechanics is introduced in this paper, and the relation between internal force ＂s change and external force ＂s direction is established. The above method is accepted by most students and desired effects are acquired during practical teaching process.

关 键 词：内力图 直接画法 内力 外力
