The results found that: ( 1) the transverse corner field resulting from the uneven geometrical width of YBT model leads to the non-uniform spreads and distributions of the active lengthwise tensile stress, the stretchy strain and the passive transverse pressure stress in the principal axis;

由此得出：①YBT模型几何宽度不均匀所形成的横向角部区域，导致了主动型的纵向主轴拉应力和主轴伸长应变以及被动型的横向主轴压应力的不均匀传播与分布；
