It is shown that the eigenfunctions for the near-field and far-field are dual as they are generated by the same set of eigenvalues in general. If the boundary conditions on the wedge faces are the same, an additional eigenfunction may appear in the far-field. Moreover the dual eigenfunctions are used to derive path-independent integrals that relate the near-field to the far-field.application/pdf109998 bytesapplication/pdfzh-TW國立臺灣大學應用力學研究所奇異應力場複合楔形體路徑無關積分Singular Stress FieldComposite WedgePath-independent Integral Integral Equation複合彈性楔形體之應力奇異性及相關路徑無關積分之研究On the Stress Singularities and Associated Path-Independent Integrals for Composite Elastic Wedgereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/21590/1/892212E002096.pdf
