Introduction Steel-concrete composite beams give full play to the advantages of steel and concrete materials.
In composite beam stiffness calculation, the two materials should be translated into the same material to facilitate the calculation.
The member stress ratios (the actual components stress divide material yield stress) are shown in Table 2.

So a critical stress σf is defined that when the applied stress is less than it, the creep fracture will not occur, and when the applied stress is greater than it, the creep deformation will continue until the creep fracture in Curve 2, dashed line.This critical stress is called the long-term strength of materials [2].
At this point there is only one sticky component in the model, and its constitutive equation is: (10) It can be seen that the whole creep process of materials is expressed by the model.

After entering the 1960s, with the application of new materials, new technology, new process, protective armor tanks on the battlefield the material, structure and type of continuous improvement, and make the tank armor ability have improved greatly.
This shows that even the same material, the structure of the material has important effect on its resistance to metal jet performance.
Use of smaller amounts of materials and the optimization of the structure of the form, improve the performance of metal jet penetration resistance, this work to continue to study and to deepen.
