As a demonstration, Fig. 1(a) shows that triangular finite element
meshes cover a material region that is indicated by a solid line.
If the crack is stable(i.e. the effective SIF falls below the material toughness), the propagation stops.

After adsorption, the adsorbate-laden materials were first washed in redistilled water and then desorbed in 300mL 80% aqueous ethanol, shaken for 3 h at 50 ˚C until desorption equilibrium, and the concentration of crude extract in the liquid phase was analyzed by HPLC again.
So the ratio of raw material to resin was set at 20:1 (w/w).

Materials and Methods
A 1:4 cement sand mortar was the initial objective for this experimental project.
The materials utilized were river sand and grade 53 cement.
Also, the rubberized specimens contained silica fumes, fly ash and fibers and all these materials enhance the density[19].

Integrated management theory has two basic views [5]: First, the process view, by which subjects of integrated management have clear objectives of the integration, various integration elements (people, machines, financial, material, information, organizations, etc.) are integrated objects, integration activities is a system activity, integrated management is an ongoing dynamic process of adjustment; Second, the technical view, by which the essence of integrated management is to manage integrated activities to promote integration of knowledge production, dissemination and application, that is, integration management itself is a kind of technology.
