円孔を有する固定正方形板の弾性せん断座屈および後座屈強度(開学10周年記念号) Elastic Shear Buckling and Post Buckling Strength of Fixed Square Plate with Circular Holes 上野谷, 実 中村, 雅樹 小早川, 好包 P(論文) Elastic shear buckling strength and post buckling behavior of thin square plates with circular holes are investigated experimentally. The plates are subjected to uniform in-plane shearing deformations and have clamped edges and centrally located the circular holes. Ratios of the hole diameter to the plate length, d/1, 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 elastic initial buckling load, comparison of test with analysis shows excellent agreement. Experimental ultimate loads of the plates with the ratio d/1=0, 0.3, 0.5 and 0.7 are 5.60, 6.96, 6.67, and 6.45 times of the initial buckling load, respectively. 1985 jpn departmental bulletin paper https://fukuyama-u.repo.nii.ac.jp/records/7691 AN00217655 福山大学工学部紀要 7 56 62 https://fukuyama-u.repo.nii.ac.jp/record/7691/files/KJ00005781028.pdf application/pdf 560.0 kB 1985-01-01
