 note = {Free vibration of an annular sector plate simply supported along the radial edges is examined. Natural frequencies of the annular sector plate with different boundary conditions along the circular edges are obtained for wide ranges of the aspect ratio. Numerical results are compared with the frequency of the corresponding rectangular plate. It is concluded that the frequency of the annular sector plate with free circular edges cannot be estimated by the rectangular plate analogy., 長崎大学工学部研究報告, 19(32), pp.67-70; 1989},
