They concluded that the presence of tensile forces had a pronounced effect on surface cracking and the cracks were originated in the low-spread regions to relieve the tensile
stress since longitudinal elongation of these edge regions exceeded the ductility of the material. Moreover,

他们的结论是，存在的拉伸力有一个显着的表面裂纹的影响，并起源于低扩散区域，以减轻拉伸裂纹由于这些边缘区域的纵向延伸的应力超过了材料的延展性。此外，
