Abstract
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.
Claims18
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.
An extensometer assembly comprising:
- a first extensometer positionable on a first side of a specimen, and comprising a first arm and a second arm pivotally coupled to each other at a proximal end, and engageable with a specimen at a distal end thereof about a specimen contact member;
- a second extensometer positionable on a second side of a specimen, wherein a second side of a specimen is opposite the first side of a specimen, and comprising a first arm and a second arm pivotally coupled to each other at a proximal end, and engageable with a specimen at a distal end thereof about a specimen contact member;
- and
- an attachment assembly configured to attach the first extensometer to the second extensometer, the attachment assembly comprising:
- a first clip having a first end coupled to the distal end of the first arm of the first extensometer and a second end coupled to the distal end of the first arm of the second extensometer, wherein the first clip extends one of substantially oblique and substantially parallel to the specimen contact member, to, in turn, facilitate attachment of the extensometer assembly in an orientation wherein the specimen contact member is substantially parallel to the direction of a force that is to be applied to the specimen and in an orientation wherein the specimen contact member is substantially perpendicular to the direction of a force that is to be applied to the specimen;
- a second clip having a first end coupled to the distal end of the second arm of the first extensometer and a second end coupled to the distal end of the second arm of the second extensometer, wherein the first clip extends one of substantially oblique and substantially parallel to the specimen contact member, to, in turn, facilitate attachment of the extensometer assembly in an orientation wherein the specimen contact member is substantially parallel to the direction of a force that is to be applied to the specimen and in an orientation wherein the specimen contact member is substantially perpendicular to the direction of a force that is to be applied to the specimen.
