Meat color is positively to marble vein, cooking percentage and shear force value(P<0.05);
肉色与大理石纹、熟肉率、剪切力值呈显著正相关（P<0.05）；
The gap of shear force among finite element simulation, the tested value and calculated value, the results confirmed the correctness of finite element simulation.
有限元模拟得到的剪切力与实测值和经验公式计算值差距很小，证实了有限元模拟结果的正确性。
A solid, however, no matter how plastic it is, dose not flow unless the net shear force on it exceeds a certain value.
但是，对于一种固体，无论其塑性如何，除非所受剪切力超过了某一限值，否则不会流动。
