Based on the research of nonlinear material model for steel fiber conc rete, using the method of increment, with experimental results and theories co ncerned, the relations of numerical constitutive model for steel fiber concrete are established.
In this paper, the basic theory and researchful methods for EOS(equations of state)of solid, liquid and gas are stated in detail. EOS of mixture is also generalized more systematically. Two models, Equivalent material model and Mixing phase model, which can describe solid-liquid transition of mixture, are presented too.
This was the motivation for the development of an appropriate material model for these materials.
For the simulation of this experiment the material model presented in this paper was used.
So far, it has been found that an elastoplastic material model based on the isotropic yield criterion of von Mises reasonably well captures the behaviour of HPDC components subject to both axial loading and 3-point bending.
These high-temperature parts deformed more easily than other parts, which is believed to be the main cause of SPS fast densification, according to a hard-core and soft-hell material model.
Serial material model (Dilute model)and Limited Units (LU)method were employed to analyze the performance of binary piezo-composite system.
