... in the structure. This paper is mainly concerned with aspects related to the material's resistance to crack propagation, i.e. the arrest toughness. Further, crack propagation is assumed to be dominated by cleavage fracture, i.e. ductile fracture and fatigue are not considered. The relative importance...

... Abstract Run-arrest behavior of brittle crack in steel has been investigated since a lot of severe accidents by brittle failure. In order to evaluate arrest toughness of materials, various test methods were developed. In 2014, arrest toughness evaluation standard which determined the test...

... Abstract The test method of the standard K ca test, so called temperature gradient type ESSO test, is one of the most popular test methods for evaluation of brittle crack arrest toughness. Test conditions which are specimen width, tab plate shape and applied stress affect brittle crack...

... Abstract In case impact energy in a brittle crack arrest toughness test is excessively large, the impact energy gives conservative test results. In this research, effects of impact energy on arrest toughness, K ca , of in crack arrest toughness specimens were investigated by dynamic elastic...

... and extremely important that a backup brittle crack arresting function is provided to arrest its propagation and to ensure structural reliability. As an evaluation method of arrest toughness, several test methods have been developed: Robertson test (1953), ESSO test (1955), Double tension test (1958) and others...
