  1. A new type of viscoelastic stochastic finite element method is established using first - order perturbation theory based on local averaging method of random field and karhunen - loeve expansion theory of random process. the amount of computations is greatly reduced by transforming correlated random variables to a set of uncorrelated random variables. the relations of different random response variables are analyzed and monte carlo simulations for viscoelastic stochastic structures are investigated

    基於隨機場的局部平均法以及隨機過程的karhunen - loeve分解理論,通過一階隨機攝動方法建立了考慮材料近似不可壓縮的粘彈性隨機有限元公式,由相關結構分解減少計算量,分析了各結構隨機響應量之間的關系,給出了數字特徵的計算方法,研究了粘彈性隨機結構的montecarlo模擬驗證方法。
