计算机屏幕显示梁的主应力迹线

Showing Beam′s Principal Stress Trajectories on the Screen of Computer

通过引入奇异函数,给出了求解梁在不同类型荷载组合作用下其约束反力、内力的通用表达式;并借助电子计算机的计算与绘图功能在 IBM-PC 微机屏幕上直观地图形显示出梁的主应力迹线。

Via introducing the queer function,gives the general expressions of beam′s binding and reacting force and internal force under the combinatorial effect of various loads,and audio-visually shows the beam′s principal stress trajectories with the aid of the calculation and map-drawing functions of IBM-PC micro-computer.
