Crack Growth in Duplex Plates

  title={Crack Growth in Duplex Plates},
  author={Emmanuel E. Gdoutos},
The problem of growth of a crack in a duplex plate perpendicular to the junction of its two sections is studied. The process of initiation, stable and unstable crack growth is analysed by assuming that material elements ahead of the crack tip fail when they absorb a critical amount of strain energy density. The critical stress at instability is calculated from the condition that the last increment of crack growth reaches a critical value. The dependence of the critical stress on the mechanical… CONTINUE READING
