NLIGA
Open source Matlab code for nonlinear isogeometric analysis
...Newton-Raphson method is used to solve the nonlinear governing equations. A series of benchmark examples are performed to validate the procedures. The visualization procedures are also developed to visualize the obtained results including displacements, stresses and numerical errors.
