摘要: The present paper deals with the problem of evaluation softening mechanical response cohesive materials under tensile loading. A nonlinear fracture mechanics approach is adopted. new numerical procedure developed to study evolution crack processes for 2D solids. proposed algorithm based on derivation and use resistance curve, i.e., R-curve, it takes into account presence process zone at tip. In fact, assuming a constitutive law interface, able determine length hence any material structure. Numerical applications are studying damage behavior infinite solid periodic distribution. Size effects investigated ductile-brittle transition characterized by same density studied. results obtained adopting in good accordance recovered through step finite element analyses. Moreover, computations demonstrate that simple efficient.
