Extensometer assembly for use in material testing systems

摘要

An extensometer assembly for use in association with a material testing system. The extensometer assembly has a pair of extensometers each of which includes a first arm and a second arm. The arms are pivotally coupled together through a connector, such as a flexure bearing. The extensometers may be positioned on opposing sides of a specimen to be tested. A pair of clips extending between opposing first arms and opposing second arms, respectively, retains the extensometers engaged to the specimen on opposing sides of the specimen.

1. An extensometer for use in association with an extensometer assembly comprising:
a first arm having a proximal end and a distal end, and a bearing bore positioned at the proximal end thereof, with a specimen contact assembly positioned at the distal end thereof; a second arm having a proximal end and a distal end and a bearing bore positioned at the proximal end thereof, with a specimen contact assembly positioned at the distal end thereof; a flexure bearing extending between the first arm and the second arm at the proximal end of each of the first arm and the second arm and into the bearing bore positioned at the proximal ends of each of the first and second arms, so as to position the first and second arms in a side by side orientation; and at least one sensor assembly having a component coupled to each of the first arm and the second arm, the at least one sensor configured to sense relative pivoting of the first arm and the second arm relative to each other.
