1 foreword composite material is a basis two plant or two kinds of above have different chemistry or the new-style material that the constituent stuff place of physical character makes, had with constituent material not identical character [1] . Composite material has quality the light, taller than intensity, quantity that compare a pattern is big, mechanical can design all sorts of specific features such as gender and fatigue resistance, had applied in spaceflight aviation, shipbuilding, car, building and chemical industry to wait for all sorts of production domains widely. In the domain of actual structure application of aerospace, applied composite material can make the quality of aviation material apparent reduce, improve pneumatic well function and improve structural efficiency and service life. The composite profile of traditional pattern expects development uses the means that the recipe explores, the design gives the composite profile with meticulous structuralization to expect, existing research and development is periodic cost of long, development is advanced all sorts of defect. Apply however finite yuan the law can use emulation technology to achieve function analysis and the goal that optimize a design to material, the real cost that reduces manufacturing research and development thereby and shorten corresponding manufacturing research and development is periodic. Design of 2 composite material applies a method to be among the analytic law of macroscopical level, hypothesis material is what distributing equably, the average performance performance that regards composite material as the substantial influence of each constituent material will undertake mature. All sorts of type parameter of material define Yu Hong to watch the respect of measure to go up, it is the some on macroscopical measure is planted average, call its apparent parameter. Use the method of macroscopical analysis, will form relevant question, analyse an accurately computation to get according with actual result to use homogeneous materials to execute firstly; Keep the design that change overly to can be brought about secondly [2] . Between law of microcosmic level analysis, think material is the characteristic that presents much constituent, and study the interaction with each constituent relevant data. Use blame all pledges mechanical method narrates each medium real stress field and field of meet an emergency, the compose on the foundation that assumes in some part establishs an analytic pattern, with imitate, analysis and the macro-mechanics character that forecast composite material. Application analyses a method this kind to existing all sorts of problems, it is micro mechanics firstly finite of yuan of model appearance is an Utopian microcosmic type construction, be not the structure of pragmatize however, cannot consider the random sex of distributinging state of the fiber in actual structure and limitation for example; It is fiber secondly / the interfacial machinery of matrix and hot property knowledge are insufficient, the stiffness attribute with corresponding interface cannot be in quite microcosmic and finite yuan of model is medium be able to reflect; Build model of three-dimensional micro mechanics to need to expend time for compose thirdly. The Helius of of emulation analysis process of 3Helius is a kind of composite material that by American Firehole the company undertakes an analysis technically to spaceflight aviation composite material and development gives analytic technology, use much constituent to analyse a technology to realize corresponding mechanical research [3] . Its roughly analytic flow is as follows: ⑴ definition is narrow the place with yuan of relevant analysis requires an input, include MCT to analyse wants standard mode project to check data to wait. ⑵ is handed over finite yuan seek solution implement have consideration, between this essence process, helius: MCT subprogram is finite yuan what the analysis offers data of this compose concern data and stress of the constituent that finish / the extraction computation of meet an emergency. ⑶ is executed finite yuan of aftertreatment. Can examine individually statified and corresponding the information such as the stress at each constituent, meet an emergency and invalidation factor. The technical implementation of 4Helius analyses 4. Stress of 1MCT much constituent decomposes the attaint of technical composite material to be able to happen on microcosmic level above all, and can be executed with the mode that asymptotic destroys expand, the local loss that includes matrix and patulous, fibrous is local happen rupture wait for a respect. To can assure to forecast the mechanical behavior of all sorts of essence of composite material accurately, need compose builds the micro mechanics model that gives composite material, execute imitate by much constituent angle, however the corresponding method of the macroscopical analysis of traditional pattern and microcosmic analysis cannot quite accurate imitate gives these attaint cases. 4.
2MCT " former " technology of material attribute extraction because of composite material shape technology differs somewhat, for instance solidify temperature, pressure, be out of shape what wait for a respect with chemical environment is different, so the attribute of this kind of material of the material attribute of each constituent in composite material and odd constituent is existing the distinction of certain level. In composite material finite yuan among analytic process, the material attribute that how narrates each constituent still is existing the difficulty of certain level. Additionally distributinging body reveals the fiber in composite material the characteristic of random sex, the state that a little local fiber can appear to be contacted each other, the fiber space that has partial area however appears further, how be finite yuan it is difficult that characteristic of this kind of random sex is narrated to be able to be compared relatively in the model, and to fiber / the interface of matrix and the relevant theory that heat up attribute are not much, stiffness attribute of the interface cannot be in quite microcosmic and finite yuan corresponding description gets in the model [4] . 4.
The evolution of advance gradually injury with efficient and accurate 3MCT analyses Helius to give the average stress of each constituent and the greatest strain according to the extraction in composite material, the scathing evolution that will calculate data thereby and follow-up destroy a state [5] . It is with composite material of one-way fiber aggrandizement exemple, when MCT asymptotic injures an analysis, application includes state of 3 kinds of injury normally, did not happen for matrix and fiber firstly destroy; Rupture for matrix happening secondly and fiber did not happen rupture; Happen for matrix and fiber thirdly rupture. However of traditional pattern finite the 2nd matrix happening that cannot consider injury quite ruptures and fiber did not produce yuan of analysis method the phase that rupture, ought to apply MCT asymptotic to injure evolution to undertake corresponding analysis, ability is OK the whole injury process of composite material of separate out of more accurate cent, make in fiber / the asymptotic injury of matrix level analyses trend at accurate with reasonable result, first when can break through traditional pattern composite material to analyse thereby destroy corresponding confine character, achieve the goal that material makes full use of, undertake decreasing weighing designing. The fundamental that the article introduced new-style MCT much constituent to analyse a technology mixes 5 last words main technique characteristic. Through applying MCT much constituent analyses a technology, can obtain each constituent information of structure of composite material interior, the stiffness that can forecast composite material well and truly and asymptotic injure evolution process, this technology attaint mechanism research to spaceflight aviation composite material and decrease heavy design to have quite enormous real sense.
