A mesoscale quantification method of cavitation in semicrystalline polymers using X-ray microtomography

► X-ray microtomography to quantify cavitation in strained semicrystalline polymers. ► Method based on correlation of the linear attenuation coefficient with 3-D porosity. ► Validation of the mesoscale quantification method. ► Application: cavitation process investigation in PVF2 from unloaded specimens. ► Effect of the triaxiality ratio and of the stretching degree on cavitation process.
