摘要
The thermoelastic plane problems of two-dimensional decagonal quasicrystals(QCs)are systematically investigated.By introducing a displacement function,the problem of thermoelastic plane problems can be simplified to an eighth-order partial differential governing equation,and then general solutions are presented through an operator method.By virtue of the Almansi′s theorem,the general solutions are further established,and all expressions for the phonon,phason and thermal fields are described in terms of the potential functions.As an application of the general solution,for a steady point heat source in a semi-infinite quasicrystal plane,the closed form solutions are presented by four newly induced harmonic functions.
The thermoelastic plane problems of two-dimensional decagonal quasicrystals (QCs) are systematically investigated. By introducing a displacement function, the problem of thermoelastic plane problems can be simpli- fied to an eighth-order partial differential governing equation, and then general solutions are presented through an operator method. By virtue of the Almansirs theorem, the general solutions are further established, and all expres- sions for the phonon, phason and thermal fields are described in terms of the potential functions. As an application of the general solution, for a steady point heat source in a semi-infinite quasicrystal plane, the closed form solu- tions are presented by four newly induced harmonic functions.
