Introduction With the rapid development of materials science in the 21st century, many materials are effectively applied to the research on life sciences.
And the research on life sciences also can not develop well without the development and application of materials.New materials are not only the significant parts of modern high science and technology but also the important pillars and breakthroughs of developing high and new advanced technology.
(Composite materials with hydroxyapatite and epoxide-acrylate-maleic anhydride is abbreviated by EH composite materials.)
Prospect.In recent years,with the rapid development of materials science,the research on nano materials and nano technology has become a new field which attracts many scientists.Nanometer materials with the characteristics including interface effect, small dimension effect and quantum dimension effect may form a stronger biological bonding between the structures replaced and bone tissue.If nano biological materials are used to make aritificial ossicle structures, an excellent biocompatibility,superior performance and long-term post-operative stability will be likely to be brought to aritificial ossicles ,which will serve human beings better.

So the disqualified machining dimensions, material property are the main reasons for the fraction of this crankshaft.
The microstructure of the journal central section was tempered sorbite and many ferrolites, and it is shown that the segregation was existed heavily in the material, as shown in Fig. 5.
It can be seen that the chemical compositions of the material are within the specified range.
FEA Simulation With the development of science and technology, FEA is receiving more and more applications in engine.
(3) The microstructure and the non-metallic inclusions of the material don’t meet the specification; these will reduce the endurance bending strength of the material, so it aggravated the fatigue fracture process.
