Prediction Of Elastic Properties Of Solids Contains Irregular Shapes Cracks

With advanced composite material appearing and computer science and technology developing, people could choose specifically microstructure for material in the past in the area of using material, but at present, man can design material for specifically microstructure. As it is not avoid in material that microcraks created in manufacture process. We must take microcracks into material process account. When the microcracks contains in the material, it is importance in design material that forecast material properties.In general material is assumed to ideal material which contains no holes or no microcraks. With researchs go deep into damage mechanics and fracture mechanics, men find it closely relates to the microstructure that material contains microcracks in the transfiguration mechanics and damage mechanics and fracture mechanics etc. It tight relates to macroscopic and microcosmic and mesoscopic on multi-scopic and multi-mechanism, but traditional research method is not done to this problems. As a branch of the mechanics mesomechanics resolve mechanics problems with continuous medium mechanics. We must relation the microstructure to it for resolve the fracture problem at all. To resolve it we must take the size of crystal grain into account at microscopic, only to this, it can direct prediction of properties of material. M. Kachanov and other men set a series of mechanical model to forecast properties of material which contains microcracks. Therefrom, men can easy forecast properties of material which contains regular figure microcracks. In fact, the figure of microcracks contains in material is irregular at all. The properties of irregular microcracks has not fix quantify formula. The present work focused on software which can resolve the problem. The software is a tool which can forecast properties of material contains irregular figure microcracks.The method of partition polygon is Innovation, especially on the algorithm of polygon circum-ellipse and the algorithm of vision vertex and the algorithm of fill triangle area in inscribed circle. It testified success through months running, the exploitation of software Csforecasteris is success.
