mechanical testing systems
Materials testing is a respected and established branch of engineering that has improved its significance over the last years immensely. The wide range of materials and their application has led to a variety of new problems and their solutions. More and more properties need to be investigated as well as stochastic evaluation approaches need to be determined and all needs to be available in a suitable and structured manner.
The brand-new LINOVIS® testing system is the most comprehensive electro-dynamic testing machine up to date. With its wide testing application, from static to highly dynamic testing for almost all materials at unmatched precision and with longevity in mind. The system is, of course, fully compatible with our VALIMAT® software solution via the built-in touch control panel.
IMPETUS® is our efficient economic stand-alone solution for dynamic materials testing. It is suitable for almost all polymeric materials, composites, foams and light metals. With its desktop-size and no prerequisites necessary, its use-cases are almost limitless.
Adding in our software solution VALIMAT® and our well-established Autofit-process and nothing stands in your way of generating fully automated crash-focused material cards!
