One can also deform the honeycomb.It is important to constrain it carefully, because the deformation behavior is complex.For example,a piece of honeycomb under cylindrical bending shows two curvatures as illustrated in Figure 4.13. This phenomenon is due to the Poisson effect,particularly sensitive here (see Section 12.1.4). 2003 by CRC Press LLC4.4.2 Processing Aspects The processing of the honeycomb is done with a diamond disk (peripheral speed in the order of 30 m/s).
