WebThe generalized differential quadrature method together with the Newmark-beta scheme is utilized to solve the non-linear partial differential equations in spatial and time domains. The resulted non-linear algebraic equations are then solved using the modified Newton–Raphson method. WebFEA: Newton-Raphson algorithm for Dirichlet BC non-linear static analysis.
