High Capacity Tensile Impact Testing
When approached by a customer for a tensile impact test of metal parts we recommended a CEAST 9350 with optional High energy system. We developed a custom fixture with integrated 30kN load cell, dedicated tup for high rate tensile impact tests DAS 64k and VisualIMPACT software.
Samples were manufactured specifically for the vice and were either 130x65mm or 80x40mm in geometry and 0.5mm thick. The CEAST 9350 provides test velocities up to 24m/s and allows the investigation of the tensile properties at high rates.
Sample tests showed failure loads in the region of 20kN at 6m/s. The fixture could also be utilized for testing composite materials and large plastic specimens.
The 9350 is well suited for helping customers determine the performance characteristics of their materials when subjected to an impact event. The information gathered by doing instrumented impact testing can be used to provide the customer with a data baseline whereby they can determine how changes made in the mix of raw materials will perform in real life situations. A broader range of testing could be accomplished with the inclusion of an environmental chamber to study impact characteristics at different temperatures as well as using different fixtures and inserts to simulate other unsupported spans and impact events.
Impact resistance is one of the most important properties for component designers to consider, as well as the most difficult to quantify. Impact resistance is a critical measure of service life and more importantly these days, it involves the perplexing problem of product safety and liability. With the combined experience of Dynatup® and CEAST, Instron® has more than 80 years experience in designing impact testing systems to simulate real-life impact conditions.

The new CEAST DAS 64K is a state-of-the-art Data Acquisition System designed for impact testing instruments. Compatible with the full range of CEAST impact testing systems, including pendulum type machines (CEAST 9000 Series) and drop towers (CEAST 9300 Series), it’s the key for instrumented impact testing. The DAS 64K also enables the data collection from instrumented tups or hammers on older models and non-CEAST impact machines.
