Abstract This thesis is concerned with the application of complex analysis for the -etermination of the small deflection of a thin circular plate supported along :nc,entric circles and acted upon by one of the following normal loadings: ’ a concentrated load at a point lying inside the inner support circle. (2) a concentrated load at a point lying between the two support circles. (3) a concentrated load at a point outside the outer support circle. (4) a uniform load extending along a third concentric circle lying between the two support circles. Exact expressions in infinite series form are obtained for the deflection in the previously mentioned cases. Limiting cases are investigated in details and results obtained are in agreement with those obtained before. The special case of a thin circular plate :Upported along its boundary, singularly supported at its centre and eccentrically loaded -with a concentrated load was solved in a different manner and its results reduce to those obtained before. Numerical results for the deflections, moments and shears are presented in tabular form and graphs illustrating their variation along various radii of the upper half of the plate are provided. |
