As a result, many studies have been conducted to assess the forming limit curve (FLC) of tested materials experimentally and theoretically.
Fig. 3 shows the experimental stress-strain curve for the tested materials.
According to this figure, the FLCs predicted by the NADDRG equation are overestimated for all examined materials.
It can be applied to estimate the FLC for other industrial materials with ease.

On the other hand, when the materials passed through the small gap of between the planetary screws and the center screw bottom, they were suffered from much higher shear rates, squeezing and stretching action due to the periodic perturbation in the space and speed, thus the dispersion of the materials were improved.
The experimental materials and formulation were shown in Table 2 and Table 3.
Table 2 Experimental materials name type manufacturer active nanometer CaCO3 GCC-R Qingxin Shuang Rong Chemistry Co.
In summary, no obvious difference in dispersion of CaCO3 is found, but the material were suffered to the much stronger shear rates in the intermeshing zones of the twin-screw extruder, and larger ratio of the length to the diameter also increased the residence time of the materials.

Experimental material and method Experimental material is X80 pipeline steel, whose chemical compositions and mechanical property are following in table 1.
Thus the composition of inclusions inducing nucleation of intra-granular ferrite depends on deoxidation and desulfidation alloyed elements in the steel and welding materials.
