正方形孔を有する固定正方形板の弾性せん断座屈に関する実験的研究 Experimental Study on Elastic Shear Buckling of Clamped Square Plates with Square Holes 上野谷, 実 中村, 雅樹 弾性座屈 せん断荷重 正方形板 正方形孔 elastic buckling shear load square plates square holes P(論文) Elastic shear buckling strength and post-buckling behavior of square steel plates with square holes are investigated experimentally. The plates are subjected to uniform in-plane shearing deformations and clamped along plate edges. The square holes are centrally located. Ratios of the hole length a to the plate length l, a/l, are 0.3, 0.5 and 0.7. Comparisons are made with previously reported analytical results. 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 elastic buckling load, test results show good agreement with analysis within 14%. Experimental ultimate loads of the plates with the ratio a/l=0, 0.3, 0.5 and 0.7 are 5.40, 5.90, 3.27 and 1.57 times of the elastic buckling load, respectively. 1990 jpn departmental bulletin paper https://fukuyama-u.repo.nii.ac.jp/records/7771 AN00217655 福山大学工学部紀要 12 79 88 https://fukuyama-u.repo.nii.ac.jp/record/7771/files/KJ00005781150.pdf application/pdf 600.2 kB 1990-01-01
