 note = {線型粘弾性特性を有する周縁固定の浅い球形殼の軸対称動的挙動が数値的に解析される.動的挫屈の定義が提案され,まだ,動的挫屈,静的挫屈およびクリープ挫屈の関係が,これら3者は時間の函数として連続的に捉えられるという事に注目して,明かにされる.更に,解析の妥当性を検証するために行われた若干の実験結果が述べられ,解析は満足すべき精度を特つことが示される., The axisymmetric dynamic response of viscoelastic clamped shallow spherical shells to transient pressure loading is analyzed analytically and experimentally. The nonlinear governing equations derived by the authors are solved numerically, and the critical load and the effects of viscoelasticity and loading speed on the dynamic behavior of the shell are discussed. The definition of the dynamic critical load is proposed. And, it is pointed out that the buckling phenomena have to be analyzed paying an attention to the connection with the time, because the dynamic, static and creep bucklings are related with one another as a function of time. In order to observe the response of viscoelastic spherical shells to the dynamic loading and to check the results of the numerical solution, some experiments have been carried out and a good agreement between the theoretical and experimental values is seen., 資料番号: SA0125502000},
