Abstract: A rectangular, singly curved and finite strip element for curved
sandwich dynamic analysis is developed. The convergence and
speed of the method, the strip element density and the reduction
of the degrees of freedom etc. are discussed through free
vibration analysis of a honeycomb cylindrical shell panel. The
results show that the frequencies and modal shapes obtained
agree very well with the analytical solutions for the
symmetrical honeycomb sandwich under the simply supported end
conditions.
