“…the lower limit on n in Eqn. (7) was -N rather than 0. Ripples are visible at the inclusion/matrix boundary which can -as for the layered material in Section 3.1 -be regarded as an example of Gibb's phenomenon, resulting from the sharp change in modulus between the two phases.…”

“…As a result, it is necessary for the general case to explicitly include the negative frequencies in the summation of Eqn. (7). However, due to the even/odd symmetry of the cosine/sine functions, only one of the two indices m and n needs to take negative values.…”

“…In works that do not use iterative process, natural frequencies and mode shapes, or operational frequencies and modes, are input data of an algorithm based on the differential equation that governs the transversal vibration of sample in a specific direction and under specific boundary conditions (Gibson, 2000;Alfano & Pagnotta, 2007). In this methodology, it can be included the use of Virtual Fields Method, VFM (Grédia, 1996(Grédia, , 2004Grédiac & Paris, 1996;Grédiac & Pierron, 1998Pierron et al, , 2007Grédiac et al, 1999aGrédiac et al, , 1999bGrédiac et al, , 2001Giraudeau & Pierron, 2003Chalal et al, 2006;Toussaint et al, 2006;Pierron et al, 2007;Avril et al, 2008;Giraudeau et al, 2006). For VFM, weighting functions are the called virtual fields.…”

“…Joint projects between medical and engineering groups should be established in the near future to help solve these very important and challenging problems. A first application of the VFM in this area was published recently [25] and a project is presently underway with Loughborough University on the measurement of the stiffness variation of cornea in the throughthickness direction using optical coherence tomography-based techniques [26].…”
