WebThe formulation remains variationally consistent but coercivity is lost with the absence of such stabilization, namely system stiffness matrix will become singular. 2.3. IGA discretization It is known that the predominant technology that is used in CAD systems to describe geometries is NURBS. Webwhere Cc is the linear damping feedback gain matrix, Kc is the linear stiffness feedback gain matrix, and Gc is the nonlinear feedback control vector. By incorporating the control (8) into the uncontrolled system, Equation (6) is rewritten as (9) where C = C0 + Cc, K = K0 + Kc, and G = G0 + Gc.
