Joining High Strain Rate Testing

Welding and bolting are widely used techniques to join metal components while adhesives are increasingly popular as a more cost-effective joining method while offering a better reduction in vibration noises and improving aesthetics of vehicles. The constant demand for new materials that are lighter or stronger necessitates advancements in joining techniques, which facilitate the joining of new combinations of materials and have potential contributions to the overall lightweighting of a vehicle. Materials exhibit different behavior under high strain rate conditions. Therefore, by investigating materials and their corresponding joined structures at various strain rates, engineers are able to understand the merits of new materials and joining techniques against established methods during crash impacts, validate and improve upon existing crash simulations.

In order to accommodate investigation of joined structures in high strain rate impact, Instron provides a wide range of accessories that will allow mounting of various structures, including any offset mounting and custom fixtures. Instron VHS also includes a high-stiffness frame that will provide greater repeatability and higher system resonance and t-slot tables come as standard on all VHS systems for easy mounting of components, providing a reliable and fully integrated high strain rate testing solution that is intuitive to use.
