Elliptically delaminated buckling near the surface of piezoelectric laminated shells under electric and thermal loads

This paper reports the result of an investigation into the local buckling for the delimitation of an elliptic shape near the surface of piezoelectric laminated shells, where local delaminated sub-shells may be monolayer and multiplayer, and the geometrical axes of elliptically delaminated sub-shells are inconsistent with the geometrical main axes of piezoelectric laminated base-shells. From example calculations, the effects of the geometrical and physical parameters, stacking models of piezoelectric laminated base-shells, elliptically laminated sub-shells, and coupled electric and thermal loads on the local buckling for elliptically delaminated sub-shells near the surface of piezoelectric laminated base-shells are described and discussed.
