Strengthening of copper materials is ensured by the addition of doping elements due to thermal or mechanical treatment.
In this connection, there was a great interest in the production of ultrafine-grained materials (UFG) by methods based on intense plastic strain (IPS) [2, 3].
This group is covered by the choice the selection of new materials for dies, processing of stamps by surface engineering technologies [4].
A great contribution to the development of the elimination of the adhesion interaction between the materials of the billet and the tool was made by the following Russian and foreign scientists: I.V.

The material was easier damaged with the bigger dip angle.
(3) The yield strength of the material decreased with increasing the sample’s dip angle, whereas the shear stress of the material represent reverse trend.

Details of specimens are shown in Table 1: Table 1 Details of Specimens Material Steel Q235 Concrete C45 Geometric dimensions Concrete columns Height（mm） 250 Width（mm） 250 Concrete beams Height（mm） 250 Width（mm） 200 Reinforcement Concrete columns Force reinforcement 4Φ12 Stirrup reinforcement φ6@100 Concrete beams Force reinforcement 4Φ12 Stirrup reinforcement φ6@100 Joint area stirrups φ6@100 As Fig 1 shows, concrete and steel use C3D8R unit and steel bars use T3D2 unit in the analysis model of ABAQUS.
The main conclusions are as follows: (1) The calculation results have higher credibility through using ABAQUS software to simulate component stress and deformation in the premise of setting reasonable boundary conditions and material constitutive relationship
