Wavelet-based finite element simulation of alloy crack

摘要：

　　Organizations can significantly reduce defects in single crystal nickel-based alloys and plastic creep life,with the creep for the alloy in the near crack region γbent along the direction of applied stress axis was 45° angle to form raft-like structure,the circular hole defects Elongated along the stress axis into an oval,and the formation of cracks in the holes on both sides and along the direction perpendicular to the stress axis expansion.During the high temperature creep,the stress near the crack contour region with the disc distribution,along with the applied stress axis orientation angle of 45° have greater value,the stress distribution is converted to γ phase angle of 45° Raft-like structures of the main reasons.γ Phase directional coarsening.In this paper,wavelet transform and finite element analysis to simulate the change
