The formulas for calculation of normal stress under complicated loads in a compo-site curved beam with general sectional shape are derived. 给出了一般截面形状的复合曲梁在复杂载荷作用下正应力的计算公式。
Thus the directions that emerge for extremizing the normal stress are the directions corresponding to the principal stresses. 因此,产生最大正应力的方向就是相应于主应力的方向。
Stresses in the SiC are computed considering normal stress, shear stress and according to the Hoffman criteria. 根据霍夫曼判据计算了碳化硅材料的法向应力和剪应力。
After the lode disappearance, the stress of each calculation point in the road diminishes quickly, particularly the verticial stress. 当载荷消失后,路面内各计算点的应力值迅速减小,尤其竖向应力减小幅度更大。
