The GeneralizedAlpha Method x n1 =x n v n h1−2 n 2 n1 h2 2 v n1 =v n 1− n n1 h m n1 = m −1 n 1− f M n −1 f n f M n1 −1 f n1 = 1 1 2 = 3− 2 1 m = 2 −1 1 f = 1 . ● ● ● ● Second Order Accurate in x First Order Accurate in v | df/dt | = O(h) Time step size is h (constant )
● Second Order SDE Structural dynamics equation with noisy loading or with uncertain behavior of joints, damaged/buckled components etc yield (after spatial discretizations) stiff second order equations with noise in the Ito sense: dx =v dt M dv = f x , v , t dt ∑ j j =1 b x , v , t dW j m ● ● ● Complete probability space (, A, P) M is invertible. And, f(drift) and b (diffusion) are Lipschitz continuous, linearly growth bounded vector functions in x,v and t; W is a standard m dimensional Wiener Process, has an associated nondecreasing family of algebras A t (t≥t 0 ) and W t is A t measurable. x,v jointly measurable on [t 0 ,t f ] x A
