Two approaches to simulate the nonlinear material response have been applied: concentrated plasticity(Clough et al. 1965, Giberson 1967) and distributed plasticity[1,2].
Considering the complex property of concrete materials, a quadrilinear-form modal for M-φ relationships including a curvature-softening stage is suitable, in which Mcr, My, Mmax(crack moment, yield moment and the largest moment separately) and the corresponding curve become three character points and each line segment has a stiffness value(stiffness state 1- 4 in Fig. 2).

It is also important to divide the difference between fault, damage and defect of material quality parameters and design. [14] • Fault is a structural problem, a change in the system that produces an unacceptable reduction of quality
• Defect is inherent in the material.
Statistically all material will have an amount of defects but the structure will still operate at its optimum.

This passive integration is performed using multilayer ceramics technology, whereby green ceramic tapes of different materials - corresponding to the different passive functions - are laminated and co-fired usually at rather low temperatures with low loss and low melting point electrode such as Ag or Cu. [2].
Bismuth-based dielectric ceramics were well known as low-fired materials and had been investigated for the application as multilayer ceramics capacitors [3].

Introduction The friction and wear is an important factor that makes parts ineffective, while the friction and wear course mainly happen on the surface of the material, preparing hard wear-resistant coating on the surface of the material could improve the wear resistance of the material, but when increasing the hardness of the surface, the wear of counterparts increase, which make the expectancy life of the friction couple decrease.
When MoS2 in the coating rub with other material, it could form solid lubricate film which effect lubricate between two surfaces, thus improving the wear resistance.

These materials combine the intrinsic characteristics of its two constituents, metal thin layer with a semi-conductor, resulting in a new hybrid material.
Furthermore, this may have some relevance to the problems of contact materials in devices. 2.
