A Dynamic Stiffness Element for Free Vibration Analysis of Delaminated Layered Beams
Figure 3
The first two natural modes for a 2-layered beam with centrally located midplane delamination, compared with those of the intact configuration. (Element totals are based on 1 element each for the outer intact segments, and equal element divisions for the top and bottom delaminated beam segments. Delamination tips and beam endpoints are visualized.), (a): 1st mode shapes, (b): 2nd mode shapes.
