Ductile Crack Propagation Characteristics in Thin Steel Tubes
Static ductile crack propagation tests were conducted using two pressurised thin carbon-manganese steel tube specimens, and the crack tip opening angle (CTOA) was measured using digital images captured on specimen surface. The critical values of CTOA for static crack propagation decreased with crack...

| description | Static ductile crack propagation tests were conducted using two pressurised thin
carbon-manganese steel tube specimens, and the crack tip opening angle (CTOA) was measured using
digital images captured on specimen surface. The critical values of CTOA for static crack propagation
decreased with crack extension while propagating crack was short. After the crack grew up to the
distance of the tube specimen thickness, the critical CTOA exhibited nearly constant. These
tendencies were the same as those of referential data in the thin single edge notched tension (SENT)
specimens of the same tubes. Using the data of both tube specimens and SENT specimens, it was
noted that the higher crack velocities slightly reduced the constant CTOA. A global constraint factor
was calculated for each tube specimen, and the constant CTOA decreased with the increase of the
global constraint factor. In addition, a dynamic ductile crack propagation test of a tube specimen was
carried out, and a crack velocity was measured. The estimation of the constant CTOA for dynamic
crack propagation in the tube specimen was performed by using the crack velocity. |
