Purpose This program allows users to perform various types of nonlinear forced vibration analysis using Elmer and post-process the result for system identification using a single environment. Also the development of Poincare' map can be applied in the different field of application. Here an example of a cantilever beam is given with a focus on the application in structural health monitoring. The detailed results are provided in the article with title 'Performance assessment of time-domain damage indicators based on output-only measurement and Poincaré map: A comparative review on nonlinear structures'.
