铸坯表面横向裂纹是连铸坯较严重的缺陷，其对铸坯的生产和质量危害很大。
Being a more serious defect, transverse crack on slab surface is very harmful to slab production and quality.
通过三维光弹实验测定了轴表面横向半椭圆裂纹的应力强度因子（SIF），并计算了与光弹轴裂纹几何及当地应力相对应的无限大体的SIF，从而求得SIF修正系数。
The SIF and its correction factor of the transverse surface semi-elliptic crack of a photoelastic axle are tested and studied with the method of three dimensional photo-elastics.
角部横向裂纹(简称角部横裂)是连铸板坯较严重的表面缺陷之一，其对铸坯的生产和质量影响很大。
Transverse corner crack is one of the most serious problems in continuous cast slab. With a great number of cracks the slab will witness serious defects and practical operation is badly influenced.
