ABSTRACT	ESDU 72016 provides a graphical method of calculating the natural frequencies of vibration of initially unstressed flat or curved rectangular panels of sandwich construction with identical face plates. The core is assumed to have zero flexural stiffness and to be isotropic, but a moderate degree of orthotropy can be taken into account. The data are particularly applicable to honeycomb sandwich panels but also have application to other sandwich panels having cores of negligible flexural stiffness.
