円孔を有する固定正方形板の弾塑性せん断座屈 Elastjoj-plastic Shear Buckling of Clamped Square Plates with Circular Holes 上野谷, 実 中村, 雅樹 せん断座屈 有孔板 弾塑性 実験 shear buckling perforated plate elasto-plastic experiment P(論文) 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. 1987 jpn departmental bulletin paper https://fukuyama-u.repo.nii.ac.jp/records/7726 AN00217655 福山大学工学部紀要 9 51 58 https://fukuyama-u.repo.nii.ac.jp/record/7726/files/KJ00005781087.pdf application/pdf 667.8 kB 1987-01-01
