Abstract
A universal test system for determining material properties of a specimen includes a base; a force sensing element in a fixed relative position to said base; a sample holder in a fixed relative position to said force sensing element, the sample holder adapted to receive a sample; a vertically movable element for contacting the sample in the sample holder and exerting a force thereon; and a controller for controlling the vertical position of the vertically movable element; wherein the force sensing element transfers an indication of the force exerted on the sample by the vertically movable element to the controller and wherein the controller controls the position of the vertically movable element in accordance with the indication of force sensed by the force sensing element.
Claims11
A system for determining material properties of a sample comprising:
- a testing device, including a base, a load sensing element, a motor and a test apparatus, said test apparatus being adaptable to perform a plurality of different material tests, said motor being coupled to said test apparatus to drive at least a portion of said test apparatus in accordance with a selected test and said load sensing element coupled to said test apparatus to sense a force transmitted by said test apparatus;
- control means coupled to said motor for controlling the operation of said motor in response to a signal from said load sensing element;
- and
- processing means coupled to said control means and said load sensing element for processing the results of a test as sensed by said load sensing element.
