Blast o-plastic shear buckling strength and post-buckling behavior of square plates with circular holes are investigated experimentally. The plates are subjected to uniform inplane shearing deformations and clamped along plate edges. The circular holes are centrally located. Ratios of the hole diameter to the plate length, d/l, are 0.3, 0.5 and 0.7. Elastic stresses along the plate edges and the hole edges show reasonable agreement with the results from finite element analysis except corners of the plates. For elasto-plastic buckling load, comparison of test with analysis shows good agreement. Experimental ultimate loads of the plates with the ratio d/l=0, 0.3, 0.5 and 0.7 are 1.64, 1.62, 1.79 and 1.87 times of the elasto-plastic buckling load, respectively. |
