Abstract:

Crack Tip Opening Angle CTOA measurements of aluminum allow 2014-T6 Al-2014-T6 at various temperatures and the construction of the corresponding CTOA curves were performed. The CTOA curve as the crack growth criterion was used to simulate the burst pressures in Al-2014-T6 thin-walled cylinders with a longitudinal crack of different sized under thermal and mechanical load. The crack growth is simulated using nodal release method in the ABAQUS finite element environment to predict the burst pressure of axially cracked cylinders.
