In the FE models shown in the Fig. 5 and Fig. 6, the concrete and steel structures were simulated with solid elements, and the normal interaction behavior between the two materials was considered as contact connections.
Furthermore, in the case of less volume of concrete material in Scheme-2, the Mises stress of the steel plates in Scheme-2 is more uniform and of less value.

This is a novel equipment for the tests of structural mechanical properties and reliability in different materials.
So, the tests of mechanics properties of materials and structures are a very important research field.
There have been a large number of designs with new structures, new materials, and new technologies in recent years, as shown in Fig. 1.
It can execute experiments involved in big size structures and materials, real-time force loading, and simulated dynamic testing.

Material models.
This suggests that the FE model may not fully capture the thermal insulation properties of the wall's unexposed side, which could be due to taking standard values for the thermal properties of the constituent materials (especially thermal conductivity) and not incorporating the actual/tested thermal properties of the materials since they are not mentioned.

Under the definite structure, different materials and fillings will affect the natural frequency of the machine bed. 3 kinds of candidate materials (HT300.20#.20# & concrete) are selected to build different machine bed.
Conventional materials of machine bed is commonly cast iron, however it is no longer well met the modern requirements of high precision.
To reduce costs, instead of epoxy concrete, the ordinary concrete and 20# steel are proposed as the filler and the material of machine bed.

Introduction The need for construction materials that possess improved fire-resisting properties led professor Joseph Davidovits to the synthesis of new materials which he named geopolymers [1].
These materials have excellent mechanical properties and high resistance to thermal and chemical attack while their synthesis is based on the activation of aluminosilicate materials by an alkali metal hydroxide and an alkali metal salt and their transformation into a three-dimensional inorganic amorphous structure [2].
