Abstract
A universal materials testing machine is disclosed. In one embodiment, the machine comprises a plurality of grips holding a circular material specimen sheet; the grips being capable of pulling the material specimen radially outward. Each grip is connected to a force measurement sensor such as a load cell. The grip and the load cell assembly is connected to a linear actuator assembly. The linear actuator assembly comprises a motor connected to an arm that can move along a straight line. The actuator pulls or pushes the load cell and grip assembly. A camera module captures images of the specimen while being stretched or released. A data processing system gathers camera module images along with force measurements from the load cells. An analysis module running on the data processing unit computes stress and strain measurements and fits them to user selectable material model.
