Abstract:

Under the isotropic hypothesis from horizonal view in this paper, used the conclusions that the force acts on the boundary of semi-infinite plate body of theory of elasticity and uniform load acts on the cylinder, the relative force formular about the formation of scrimber blank acted by static pressure have been derived and conclusions have been verified through tests. Applied these theories, the maximum stress when wood web of scrimber are formed and reached the critical situation can be calculated accurntely, and the intensity criterion can be established. the conclusions in this paper elso can be applied to the parameters establisment of manufacturing equipment for scrimber blank as well as rich the basic theories of wood science.
