Abstract

An accurate method is presented for flexural vibrations of rhombic plates having all combinations of clamped and free edge conditions. The prime focus here is that the analysis explicitly considers the bending stress singularities that occur in the two opposite, clamped-free corners having obtuse angles of the rhombic plates. Accurate non-dimensional frequencies and normalized contours of the vibratory transverse displacement are presented for rhombic plates having a large enough obtuse angle of 165$^{\circ}$, so that a significant influence of clamped-free corner stress singularities may be understood.

본 논문에서는 고정 또는 자유 연단 조건의 모든 조합을 고려한 마름모꼴 평판의 휨 진동에 대한 엄밀한 해석방법을 제시한다. 본 논문의 주된 관점은 마름모꼴 평판 둔각 모서리의 경계조건이 고정 또는 자유일 때 휨응력의 특이도를 엄밀히 고려하여 해석하는 것이다. 고정 또는 자유인 모서리 응력 특이도의 중대한 영향력이 이해 될 수 있도록 충분히 큰 165。 둔각모서리를 갖는 마름모꼴 평판에 대하며 엄밀한 무차원 진동수와 수직 변동변위의 전형적인 등고선을 제시하였다.
