As a new fiber material, igneous rock fiber reinforced polymer(IFRP) is a cost-effective, good comprehensive performance.
No-yield-point steel constitutive model was used to describe the material property of rebar.
The mainly reasons are: (1) when wrapping IFRP to the columns, there was some disturbance to the strain gauges; (2) the constraint of simulation models and the method of loading couldn’t be the same to the experiment; (3) concrete of simulation models is a homogeneous and isotropic material, but concrete in real life is discrete and its homogeneity could be impacted by construction method.
(3) The strengthening effect of secondary-load RC square columns is closely related to the ratio of first load to the compression capacity Acknowledgements The supports of the paper by the National Natural Science Foundation of China under Grant No. 51279181 and the Science and Technology Plan Project of the Ministry of Water Resources of P.

Fig.4 Subregional analysis diagram Set the material parameters.
General material parameters typically include the relationship between viscosity, shear rate and temperature, fluid viscosity, integral-differential visco-elastic model, thermal expansion coefficient, unit mass heat capacity, density, thermal conductivity, gravity, viscous heating and so on.
It can be seen from the Figure 5, die extrusion that is section from inlet to z=100mm, the rubber material is fully developed, The end that is z=240mm to end section where speed of development is a constant value, Between the extrusion and the end that is z=100mm section to z=240mm section as a transitional stage, neither fully developed nor constant.

In generally, the magnetostriction value in magnetic materials is directly related to the magnitude of the magnetization, beside structural factors.
The origin of magnetostriction for weak ferromagnetic materials is very complex, and the further research is needed.
