several cracks on the ridge are advancing
Answers
•Ridge cracking has been shown to occur in the transverse direction in tensile fragmentation tests of coatings on PET films.
•The FEM simulations includes the inelastic deformation of the polymer substrate measured experimentally by DIC.
•The fracture energy predicted by an analytical model for ridge cracking differed with 10-20% from those predicted by FEM.
•The TiO2/PET showed higher interfacial fracture toughness values than those of the mixed TiO2 and Al2O3/PET.
Hope this will help uh☺
