چکیده
|
Due to a shock,a composite panel of a naval or aeronautical structure may have a crack. the present work is to model the behaviour of a composite panel having a longitudinal crack subjected to a bidirectional tensile loading. to stop the spread of the crack,we propose to employ stiffeners. this technique optimizes the weight of the panel and to increase its resistance. in this context,we account on the proposal for an ansys modeling for the study of the crack propagation in a composite laminate panel. our modeling take into account the effect of the load intensity,the influence of the presence and location of the stiffeners,the crack inclination angle and the influence of the material properties. following the satisfactory results obtained by the proposed modeling,our work can be used as a basis for the repair of cracked laminated composite panels after a possible shock.
