| description | This paper investigates the effects of localized interface progressive delamination
on the behavior of two-layer laminated composite plates when subjected to low velocity
impact loading for various fiber orientations. By means of finite element approach, the
laminae stiffnesses are constructed independently from their interface, where a well-defined virtually
zero-thickness interface element is discreetly adopted for delamination simulation.
The present model has the advantage of simulating a localized interfacial condition
at arbitrary locations, for various degeneration areas and intensities, under the influence
of numerous boundary conditions since the interfacial description is expressed discretely.
In comparison, the model shows good agreement with existing results from the literature
when modeled in a perfectly bonded state. It is found that as the local delamination area
increases, so does the magnitude of the maximum displacement history. Also, as top
and bottom fiber orientations deviation increases, both central deflection and energy
absorption increase although the relative maximum displacement correspondingly decreases
when in contrast to the laminates perfectly bonded state. |
