Introduction With the rapidly increasing use of composite materials and adhesive, much attention has been paid to the interfacial crack by researchers.
The fracture of composites and bonded dissimilar materials is induced mainly form the interfacial region.
It is useful to design and manufacture composite materials for which we know the fracture behavior of their interface.
Hence, problem of interface crack in dissimilar materials is very important.
The numerical solutions are discussed in the analysis of a penny-shaped crack between two dissimilar materials [1-5].

The chemical materials were above 99% in purity and used without further purification.
No precipitation of materials was observed before drying the solution in Petri dish at 80 oC for 24 h.
A broad spectrum exhibited by the sample before calcination, indicates that the dried samples demonstrated an amorphous behavior although physically appeared to behave like crystalline materials.

The unconfined concrete, partially confined concrete, highly confined concrete, structure steel and longitudinal reinforcement bars of the complex cross section can be established by OpenSees program which can define the different fibers for kinds of materials with their own stress-strain relations, respectively.
Based on fiber models, the analytical model for simulating the hysteretic behavior of SRC columns is proposed by using OpenSees program which can define the different fibers for kinds of materials with their own stress-strain relations, respectively.
The material constitutive model.
The composite section of SRC columns is consists of three materials: concrete, structure steel and longitudinal reinforcement bar.

The structure of the materials was analyzed using TEM, SEM, and X-ray diffraction.
The porosity of the materials did not exceed 1 - 3.5 %.
The Raman spectra of the materials (Fig. 4 f) demonstrated the metal-like behavior, the same as superconductors.
