Shear
The 2820-060 wood shear fixture is designed for testing
shear strength properties of wood or adhesive bonds in
wood by compression loading.
The fixture consists of a high-strength steel body with a
sliding , self-aligning anvil which is used to apply compressive loading to the specimen in shear. The shear line can be set at 0.0 mm, 2.0 mm or 3.0 mm by
using shims. The shims are clearly engraved with the
applicable standard and are easy and quick to change.
The fixture is attached to the test system using simple clevis pin interfaces which allow quick and easy fitting and removal.
Principle Of Operation
The fixture consists of two main components. A sliding shear blade with a self-aligning anvil contacts the specimen which is supported in the body of the fixture. The shear blade moves downwards under compression and applies a shear force to the specimen. The self-aligning anvil ensures uniform lateral distribution of the applied load. A screw-action specimen clamp with self-aligning thrust pad holds the specimen securely during test. Shims supplied with the fixture allow the clearance along the shear line to be adjusted according to the standard being followed. Clearances of 0 mm, 2.0 mm and 3.0 mm are possible.Application Range
