The application of 3D-digital image correlation and analytical approaches on th...
Kharrat, Fatma; Khlif, Mohamed; Hilliou, L.; Nouri, Hedi; Covas, J. A.; Bradai, Chedly; Haboussi, MohamedThe mechanical characterization of plastic films is often complicated by their relative frailty and small thickness. When practical applications involve biaxial stress loading, the bulge test seems to be the most simple and suitable approach. In this work, polylactic acid (PLA) film and biocomposites PLA films filled with 1, 2 and 5 wt% of date palm leaf filler (DPLF) obtained by extrusion film blowing were sub...
Bulge test technique and digital image correlation for the determination of the...
Kharrat, Fatma; Chaari, Rania; Khlif, Mohamed; Hilliou, L.; Covas, J. A.; Haboussi, Mohamed; Bradai, ChedlyThe bulge test is a versatile mechanical testing technique that can be used for a wide range of of applications in materials science, engineering, and biomedical research, and is a valuable tool for understanding the mechanical behavior of materials and structures. In this present work, the construction of a pneumatic bulge test apparatus dedicated to characterizing 50 micrometers-thick PLA films was detailed. ...
Characterization of PLA/Palm fiber films by conventional tensile test and digit...
Kharrat, Fatma; Mohamed, Khlif; Hilliou, L.; Nouri, Hedi; Haboussi, Mohamed; Bradai, ChedlyAccurate and reliable deformation measurements are the main pillar of materials testing. Films produced by extrusion blowing process represent a real issue in their mechanical characterization. This is because of their relative fragility and low thickness. Actually, standard methods usually result to an uncertain strain definition leading to doubtful properties determination. In this work, two methods have been...
