Daftar Isi:
- An Investigation of the effect of rolling on the fracture toughness and crack growth rate for ship steel has been performed. The testing was carried out using compact tension specimens (CTS) on the field to be investigated. The CTS orientation was chosen to be parallel and perpendicular to the rolling orientation. The fracture toughness and crack growth rate tests were conducted in accordance with ASTM standard E 399-83 and ASTM standard E 647 - 86a respectively. The test 'results show that the fracture toughness of perpendicular to the rolling direction is slightly higher than of parallel direction. The crack growth rate depends on the range of the stress intensity factor (AK). For low value of AK the crack growth rote is the same for all directions, and for high value of AK, Perpendicular to the rolling direction shows higher than parallel to the rolling direction.
