Abstract
This paper presents a finite element model based on the
Reissner-Mindlin plate theory to calculate the static load-deflection
behavior of delaminated plates. Delamination
growth is taken into account by applying a fracture mechanics
criterion which can only be checked along the
delamination front. Therefore, a so-called front control
method has to be used for the delamination growth simulation,
which is realized with a moving mesh technique
adapting the mesh successively to the delamination front.
Although the simplifications of the model compared to
the three-dimensional elasticity theory restrict the model
to Griffith-type growth criteria, qualitative delamination
growth phenomena can be described rather well.
