Abstract : In this paper, ABAQUS user define field variable subroutine option for prediction of failure load (FL), progressive stress intensity factor, and critical stress intensity factor (Kc) of a finite plate of laminated composite specimen with cutout and multiple cracks is examined. Hashin and Chang progressive damage criterion is incorporated in subroutine option to predict the damage initiation for cutouts, and hatch cover used extensively in aerospace community. An experiment is performed considering laminated composite finite plate with stress concentration to validate the subroutine predicted results. The subroutine estimated results show an excellent agreement with experimental results. Typical numerical results are presented to examine the effect of stiffness degradation, fibre orientation, crack length, material properties, and cutouts on fracture prpoerties.
