| − | Mike's PhD thesis concerned a two-dimensional floating elastic plate which was solved
| |
| − | using a Green function method. The motivation for the solution was to model ice floe
| |
| − | and at the time he was ignorant of the engineering applications (e.g. [[VLFS]]).
| |
| − | Mike independently derived the Green function which
| |
| − | was well known in water waves and goes back to [[John_1950a| John 1950]].
| |
| − | The derivation method was copied by [[Squire_Dixon_2000a| Squire and Dixon 2000]]
| |
| − | (based on a close reading of his Phd thesis) for the case, not of a free surface,
| |
| − | but for a free surface covered by a plate
| |
| − | The results
| |
| − | of this research were publised in the ''Journal of Geophysical Research'' were largely
| |
| − | ignored by later researchers. His Phd thesis probably had a much greater influence, through
| |
| − | the researchers who followed at Otago and it is continuing to appear in journal citations.
| |
| − | The solution method using a Green function coupled with a Green function for the plate
| |
| − | (the later Green function does not extend to three dimensions because of the much
| |
| − | more complicated boundary conditions which exist). The solution method has been
| |
| − | superseeded by more efficient methods, most notably the [[Wiener-Hopf]] method developed
| |
| − | by [[Tim Williams]] and the eigenfunction matching method (which applied to
| |
| − | multiple plates) developed by
| |
| − | [[Kohout_Meylan_Sakai_Hanai_Leman_Brossard_2006a | Kohout et. al. 2006]].

| − | Mike then extended the two-dimensional solution to a three-dimensional circular elastic plate
| |
| − | ([[Meylan_Squire_1996a|Meylan and Squire 1996]]).
| |
| − | This solution again used a Green function method coupled with the eigenfunctions for a circular
| |
| − | plate (which can be computed in exact form, at least up to solving an equation involving
| |
| − | Bessel functions. The solution method has been superseeded by [[Peter_Meylan_Chung_2004a | Peter, Meylan and Chung 2004]].
| |
| − | Mike also developed a method to solve for plates of arbitrary geometry, initially using
| |
| − | a variational method ([[Meylan_2001a|Meylan 2001]]) and later using the [[Finite Element Method]]
| |
| − | ([[Meylan_2002a|Meylan 2002]]).
| |
| − | | |
| − | Mike then worked on using the solution for a circular elastic plate to try and construct a model
| |
| − | for wave scattering in the Marginal Ice Zone ([[Meylan_Squire_Fox_1997a| Meylan, Squire and Fox 1997]]).
| |
| − | This model was developed independently of the model of [[Masson_LeBlond_1989a | Masson and LeBlond 1989]]
| |
| − | but shares many similarities with it.
| |
| − | | |
| − | Mike then began to work on a very abstract (and difficult problems) of an eigenfunction
| |
| − | expansion method for the non-selfadjoint operator which arises in the scattering model
| |
| − | of [[Meylan_Squire_Fox_1997a| Meylan, Squire and Fox 1997]]. This work is still
| |
| − | unpublished although a paper has been submitted. It is not a problem in water wave theory.
| |
| − | | |
| − | [[Cynthia Wang]] worked with Mike as a masters and Phd student. Her master thesis concerned
| |
| − | wave scattering by a [[Floating Elastic Plate]] on water of [[Variable Bottom Topography]]
| |
| − | ([[Wang_Meylan_2002a| Wang and Meylan 2002]]). Cynthia worked on developing a higher-order
| |
| − | coupled [[Boundary Element Method]] [[Finite Element Method]] for the three-dimensional
| |
| − | [[Floating Elastic Plate]] ([[Wang_Meylan_2004a|Wang and Meylan 2004]]) and applied this
| |
| − | method the problem of an [[Infinite Array]] of [[Floating Elastic Plate|Floating Elastic Plates]]
| |
| − | ([[Wang_Meylan_Porter_2006a|Wang, Meylan and Porter 2006]]).
| |
| − | | |
| − | Mike developed a method to solve for multiple floes using an extension of the method
| |
| − | of [[Meylan_2002a|Meylan 2002]]. This was not published but was used to test the
| |
| − | multiple floe scattering method which was developed with [[Malte Peter]] using [[Kagemoto and Yue Interaction Theory]].
| |
| − | Specifically, in [[Peter_Meylan_2004a | Peter and Meylan 2004]] the [[Kagemoto and Yue Interaction Theory]] was extended
| |
| − | to infinite depth and a coherent account of the theory for bodies of arbitrary geometry was given.
| |
| − | This work required the development of very sophisticated wave scattering code for bodies of
| |
| − | arbitrary geometry. As a direct result of this work a new expression for the [[Free-Surface Green Function]] was
| |
| − | developed and this was published separately ([[Peter_Meylan_2004b | Peter and Meylan 2004]])
