Stress intensity factors at vertical crack tips and numerical results of pressure under punch are obtained.
最后得到垂直裂纹端点处的应力强度因子和压头下方的压力数值。
Usually, layer and vertical crack are caused by moulding, and horizontal and reticulate crack are caused by sintering.
通常层裂和竖向裂纹是机压所致，横向裂纹和网状裂纹是烧成造成的。
By use of minimum quadratic multiplication the inflexion depth to temperature curve can determined that can interpret the vertical crack height.
通过逐一确定井温曲线拐点达到确定裂缝高度的目的。利用最小二乘法可以确定井温曲线拐点深度，从而可以解释垂直裂缝高度。
