Abstract
An extensometer structure includes a first extension arm having a first mount configured to support a first specimen engaging member and a second extension arm having a second mount configured to support a second specimen engaging member. A connecting member extends between the first and second extension arms and pivotally connects to each of the first and second extension arms between each corresponding mount and a remote end of the extension arm. A rear coupling assembly connects remote ends of the extension arms together.
Claims49
An extensometer structure comprising:
- a first extension arm having a first mount configured to support a first specimen engaging member;
- a second extension arm having a second mount configured to support a second specimen engaging member;
- a connecting member extending between the first and second extension arms and pivotally connected to the first extension arm with a first pivot connection and pivotally connected to the second extension arm with a second pivot connection, and wherein the first and second pivot connections are disposed on each respective extension arm between each corresponding mount on each respective extension arm and a remote end of each respective extension arm;
- and
- a rear coupling assembly connecting remote ends of the extension arms together.
An extensometer structure comprising:
- a first extension arm;
- a second extension arm movably connected to the first extension arm;
- and
- a fixing assembly coupled to each of the first extension arm and the second extension arm configured to selectively secure the first extension arm to the second extension arm together to inhibit movement of the first and second extension arms toward and away from each other.
An extensometer structure comprising:
- a mounting assembly having a first mounting block movable relative to a second mounting block;
- an extensometer arm assembly joined to the second mounting block and including:
- a first extension arm;
- and
- a second extension arm movably connected to the first extension arm;
- and
- a force generating assembly coupled to the extensometer structure with a spring element to urge the extension arms toward a test specimen.
An extensometer structure comprising:
- a first extension arm having a first mount configured to support a first specimen engaging member;
- a second extension arm having a second mount configured to support a second specimen engaging member;
- a connecting member pivotally connected to each of the extension arms;
- a first counter weight mounted to the first extension arm on a first side of the connecting member, the first counter weight of mass to offset at least some of the mass present on the first extension arm on a second side of the connecting member opposite the first counter weight;
- and
- a second counter weight mounted to the second extension arm on the first side of the connecting member, the second counter weight of mass to offset at least some of the mass present on the second extension arm on the second side of the connecting member opposite the second counter weight.
An extensometer structure comprising:
- a first extension arm;
- a second extension arm movably connected to the first extension arm;
- a first mount connected to an end of the first extension arm and configured to hold a first specimen engaging device;
- a second mount connected to an end of the second extension arm and configured to hold a second specimen engaging device;
- and
- wherein each mount and associated end of each extension arm includes a coolant passageway.
