The fatigue failure function f(σij) of different materials is different, and the influence of different stress states should be fully included, considering that most engineering structural materials are isotropic elastoplastic metal materials, under multiaxial load, f(σij) can use the equivalent force formula
For isotropic metal materials, the elastic stress distribution is only related to the notch geometry, and for anisotropic metal materials, Φ(r) is also related to the elastic properties of the material.

FTIR Analysis of the Lignin Structure Changes of APMP Treated by Laccase and Laccase /Mediator System Fan Liu1, a, Yu Liu1,2,b, Jiachuan Chen 1,c, Zhen Wang 1,d 1Key Laboratory of pulp and Paper Science&Technology of Ministry of Education, Shandong Polytechnic University, Jinan, Shandong 250353, P.
Introduction Lignin as a kind of high polymer general exist in plant ,which is supporting the growth of a plant.It is one of the important material of a plant.
This study chose wo stage pulp as raw materials on the basis of domestic and international researches , using Argyropoulos's invention of a novel lignin separation method - enzymolysis- acidic hydrolysis two stage process [1,2,3], this purification lignin has high yield, high purity, and a less structural change [4]. 1.3.1 Acetone Extraction The first extraction with acetone to be separated lignin pulp.

Uniaxial compressive strength of red sandstone water sensitivity test Contained by red sandstone structure, cement and minerals and other ingredients constitute its main strength, and the main component of kaolinite, montmorillonite and illite clay minerals and calcium cements is red sandstone, single components, these components are relatively low strength and disintegration water easily, softening, which is the red sandstone rocks compared with other materials, the reasons for poor engineering properties.
