| Abstract | ||
| The effect of hole made in plate (subjected to concentrated force) on the deflection and maximum stress is studied. Different hole sizes and distance from the plate center(x) are tested experimentally and compared with a reference plate without hole. The specimens are classified in to two groups; the first represents the specimens which contain hole leis in the x-axis of the plate and the second group represents the specimens which contain two half hole leis at the edge of plate. The results are analyzed analytically, which give a good agreement with the experimental deflection data. The first and second group with the same diameter gave a lower deflection than that for the plate without hole for the same cross sectional area. Increasing hole diameter gave a reduction in the deflection values for the specimens in each group. The second group of specimens gave a higher deflection values for a wide range of (x) as comparing with those of specimens in the first group. The maximum stress (σx) is higher in the specimens of the two groups as comparing with the reference plate for wide range of (x). When this distance (x) increased, the value of maximum stress is reduced for the specimens of the two groups. The same behavior is found when increasing the hole diameter. | ||
