The wide-plate crack arrest test under tensile load for characterizing the brittle crack arrest toughness of high strength shipbuilding steel requires high economical cost and long lead-time, so there is still a substantial industry need for the simp

Brittle fracture in carbon steel has serious impact on the fracture safety of steel structures. Thus, technology that arrests crack propagation is the final defence for these structures. Conditions that can reliably stop crack propagation should be t

The priority items in the safety evaluation of steel structural components generally include an ability to arrest crack propagation, which is necessary to prevent a catastrophic failure even if a brittle fracture occurs. The ‘double integrity’ co

Dynamic frack propagation experiment using rubber tubes has been developed which is intended to simulate running ductile fracture in high-pressure gas pipelines. Crack velocity was measured by high-speed camera. It ranged 100 to 500m/s, depending on

Brittle fracture is a catastrophic failure that must be avoided for steel structures. In order to prepare the case that brittle fracture occurs due to fatigue crack propagation from welding defects and toughness deterioration of heat affected zone, e

To observe the effect of stress triaxiality upon brittle fracture surface, we performed two types of experiments which differ in stress triaxiality. As a result, crack branch starting speed changes in two specimens and the speed was affected by stres
