Jednym z ważnych parametrów wytrzymałościowych wprowadzonych do obliczeń inżynierskich dla doboru materiałów i oceny ich własności eksploatacyjnych jest odporność materiału na pękanie. W odróżnieniu od statycznej odporności na pękanie KIc, JIc ważnym parametrem jest też dynamiczna odporność na pękanie KId, J1d, ad. W pracy na przykładzie oprzyrządowej próby udarowego zginania oceniono związek parametrów...
At first there were made characteristic of some models of hydrogen induced cold cracking. After characteristic the real conditions of the cold cracking in weld joints shows the possibilities of used the threshold stress intensity factor KIthto evaluate the cold cracking resistance There also was established a modified van Leeuwen - Lancaster equation and determined the relation KIth/KIC. In this relation...
