Abstract
In this paper, elastic buckling of a partial circle thin cilindrical shell simply supported at each end with the longitudinal edges free is investigated for the case of uniform radial loading. In the begining, buckling load qck gives an approximate analysis using the energy method. Figure 4.5 shows qraphically the results obtained for a shell with, l/r: 2.5〜3.5, t/r: 1/1000〜20/1000, φ_0: π/6〜π/2 in the next place, loading test of this type are made. An error of experimental values was a range of about 2 to 40 per cent.
