Shear beam model for interface failure under antiplane shear (II)— Instability

  • Shen Xin-pu
  • Zenon Mroz


Based on the (I) of the present work, the behavior of shear beam model at crack initiation stage andat instable propagation stage was studied. The prime results include:1) discriminant equation which clarifies the mode of instability, snap-back or snap-through, was established;2) analytical solution was given out for the double shear beam and the load-displacement diagram for monotonic loading was presented for a full process; and3) the problem of the energy release induced by instability was discussed.

Key words
