  title     = {Numerical Analysis of Effect of Crack Location on the Crack Breathing Behavior},
  abstract  = {In this work, a three dimensional finite element model was developed to investigate the crack breathing behavior at different crack locations considering the effect of unbalance force. A two-disk rotor with a crack is simulated using ABAQUS. The duration of each crack status (open, closed and partially open/closed) during a full shaft rotation was examining to analysis the crack breathing behavior. Different crack breathing behavior found at different crack locations when crack in an unbalanced shaft including single status. The breathing behavior of crack along the shaft length is divided into different regions depending on the unbalance force and crack location. The simulated results in this work can be further utilised to obtain the time-varying stiffness matrix of the cracked shaft element under the influence of unbalance force.},
