The results from experiments showed that the relationship between modulus of elasticity(MOE), modulus and Rupture(MOR) and adhesive pressure are non-linear.
结果表明，塑化杨木单板的静曲模量和静曲强度与塑化压力呈非线性关系。

The drawing process of thick wall is a problem of geometry non-linear and material non-linear, so it is very difficult to be solved by the method of elasticity and plastics mechanics.
而厚壁封头冲压成形过程属于几何非线性和材料非线性的问题，很难用弹塑性力学理论的解析法进行研究。
