Claim One:
1. An apparatus comprising: a plurality of linear actuators, load cells attached to each of the linear actuators, grippers attached to each of the load cells, a first plate, and a data collection system, wherein the grippers can simultaneously grip a material sample and pull it outwards, the grippers each have two gripping blocks configured to move on guides in such a way that as they move on the guides towards their respective linear actuator, the distance between the gripping blocks increases, the first plate is configured to contact one of the gripping blocks of each of the grippers at geometric contact points and configured in such a way that the grippers may be pushed beyond the respective geometric contact points with the first plate, causing the grippers to open, and the data collection system collects force data from the load cells and geometric data.
