The damage growth law is adopted to predict the ductile response of the specified materials. Cyclic load-unload tensile tests in combination with standard uniaxial tensile tests helped to estimate the necessary parameters: damage variable, D, fracture stress, subf , threshold damage strain, sub0 , and strain hardening exponent, n, required to apply the model. The strain hardening exponent estimated from the cyclic test data is used to predict the damage variable, D. Increase of damage shows deterioration of the hardening exponent magnitudes varying nonlinearly. The simulated flow curve by the damage variable, D, corresponding to the load- unload test is observed to approximate the experimental true stress-true strain curve very closely up to the onset of necking for both the materials. The experimental values of D, as obtained for C-Mn-440 and IFHS steels, vary from 0.10 to 0.44 and 0.09 to 0.45, respectively. The critical damage parameters, DsubC , for the considered materials are 0.44 and 0.45, representing their good ductile response"},{"@xml:lang":"sl","#text":"Duktilne poškodbe v materialu so posledica zmanjševanja togosti ob povečevanju plastičnih deformacij, vse dokler ne pride do zloma nosilnega elementa. Velja razlaga, da je mikroločevanje v kovinskih polikristaliničnih agregatih ob močnem lokalnem plastičnem tečenju posledica procesa razvoja praznin oz. votlin. Opredelitev primernih meril za poškodbe pomaga pri oblikovanju zakonov razvoja, ki so potrebni za popis duktilnega odziva do zloma za določen razred tehničnih materialov. Pristop mehanike poškodb v kontinuumu (CDM) obravnava poškodbe na podlagi efektivne površinske gostote razpok. Z uporabo konstitutivne enačbe CDM je mogoče analizirati raven poškodb pri različnih materialih in s podobnim vrednotenjem je mogoče pripraviti potrebne smernice za nadzor in zagotavljanje boljše izkoriščenosti materialov. Pristop lahko pomaga tudi pri analizi komponent po zlomu za identifikacijo vzroka odpovedi.
