When the thickness of the coating is increased, the maximum circumferential stress decreases and the stress intensity factor decrease little. 随着涂层厚度的增加,切口尖端附近的最大周向应力减小,而应力强度因子减少的很小。
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。
