Here are some preliminary results obtained with the prototype version of the iso-geometric simulation module developed in the ICADA project.

The prototype can do linear-elastic problems, static loads, linearized buckling and free vibration eigenvalue analysis.

Linearized buckling analysis with NURBS

Below the fourth buckling mode for a simply supported square plate with a center hole is shown. The analysis is performed using 2nd order NURBS as basis functions.

Free vibration analysis of stiffened plate

Below the 11th vibration mode is shown, computed using 3rd order splines as basis functions.
