Introduction Currently, steel fiber concrete is given special attention as one of the fastest growing effective and promising building materials.
It can be seen that the higher the heating temperature, the greater the relative decrease in the mass of materials.
The results of the effect of heat has on the linear dimensions of the material samples are given in (Fig. 2).
Moreover, after 800 and 1000 ° C in materials with a volumetric fiber content of 3% and 6% when using certain types of fiber, an increase in size occurs. 2.

As the changing of load material boundary conditions and other factors, one surface may contact or not contact with other surfaces in a sudden which will cause abrupt change of system rigidity; contact problem often involves in the solving of friction response, and the result is difficult to converge.
In rigid - flexible body contact problems, one or more contact surfaces are taken as a rigid body (with a much larger rigidity than the other contact surface), which is suitable for the case that soft materials contacts with hard materials; flexible - flexible body contact is suitable for the two contact deformable bodies with similar contact rigidity, which is the most common type.

The solder ball was modeled with Multilinear Isotropic (MISO) hardening model, while the other components were treated like linear elastic materials.
The figure indicates that the application of shear loads to a multi-phase structure results in the formation of a singularity phenomenon, i.e. a stress concentration, at the corner of the common boundary of two different materials [4].

As a consequence, effort must be made to mechanically characterise those materials as accurately as possible.
The classical approach in experimental mechanics of materials does not account for such phenomena in a correct manner and must be revisited.
