The formulas for calculation of normal stress under complicated loads in a compo-site curved beam with general sectional shape are derived. 給出了一般截面形狀的複合曲梁在複雜載荷作用下正應力的計算公式。
Thus the directions that emerge for extremizing the normal stress are the directions corresponding to the principal stresses. 因此，產生最大正應力的方向就是相應於主應力的方向。
Stresses in the SiC are computed considering normal stress, shear stress and according to the Hoffman criteria. 根據霍夫曼判據計算了碳化硅材料的法嚮應力和剪應力。
After the lode disappearance, the stress of each calculation point in the road diminishes quickly, particularly the verticial stress. 當載荷消失后，路面內各計算點的應力值迅速減小，尤其豎嚮應力減小幅度更大。
