两种构件正应力近似解与精确解相对误差的计算

The relative error calculation to accurate explain against approximate explain of two kinds of component's positive stress

文献［１］［２］对平面曲杆和圆柱形容器两种构件，正应力有近似解与精确解；近似解工作量远小于精确解．为工作需要，本文计算了两种解相对误差．

Plane crank and cylindrical container, to these two kinds of component’S positive stress there are accurate and approvmiate explains on the literature[1]、 [2]. The appromiate caculation is more simple and easy than accurate calculation. In this the sis we calculate the relative error to accurate explain against approximate explain of these two kinds of component’s positive stress and they will be usefull in our study.
