This tool is provided by ISFK to promote the use of the NB-test. The practical use of the test is simple, but its evaluation requires FEM-calculations which we make available here. The use of the tool is free of charge. If you use data generated with the applet (strength, pre-factor or effective regions) for your work, please cite:
