WebIn this study, the substructure is considered based on the crystal plasticity (CP) method which is a well-established approach to predict the mechanical responses of crystalline materials . This method takes into account crystallographic anisotropy and captures the underlying physics at the crystal level [ 16 ]. WebCrystallinity can be accurately measured by X-ray diffraction and less accurately but simply by specific gravity. The properties of PCTFE vary with the degree of crystallinity. Table …
