Question

Problem 5(25%): Consider an elastic membrane stretched across a rectangular frame, to which it is fixed. Suppose the frame and the rectangle it enclose occupy the region of the x,y plane defined by OSISLOSY SK. We want to determine the vertical displacement function :(.y.t). The boundary value problem for : is 82 a.) for OCICLOCyck > 0 z(,0.6) = 2(3,K,t) = 0 for 0 <=<L, > 0 z(0,y,t) = 2(L,y,t) = 0 for 0 <y< , > 0 2 (2,,0) = f(x,y) for 0 <<LOCy<K (x, y,0) = 0 for 0<x<L, O<y<K . Sol: Refer to Ch.7 on page 61-65.
