Description
The objective of this paper is to investigate mesh size effects on fracture toughness of SA508 carbon steel by damage model. To achieve this goal, a series of finite element analyses are carried out for CT (compact tension) and PCVN (pre-cracked V-notch) specimens. And Weibull stress model are adopted to derive toughness scale diagram. Finally, toughness scale diagram, which considered crack-tip mesh size effects, is derived from comparing estimated fracture toughness data between CT and PCVN specimens under -60 .deg. C and -80 .deg. C
