Wood Flexure Fixtures

Description

Bend tests provide a quick and simple way to determine the strength and deformation properties of wood and timber products. The test is also particularly relevent in
this application because wood is frequently used in the form of beams where resistance to bending is an important parameter.
A range of fixtures is available to cater for various specimen sizes and strengths. All fixtures can be
equipped with a range of optional support rollers some of which feature articulation to cater for warped specimens.
The range of fixtures is ideal for tests on MDF and fiberboard as well as natural timber.

Principle of Operation

2820-04x Series bend fixtures are designed for static bend/flexure testing on a range of wood and timber products according to common International Standards. The beam attaches to the test instrument using simple mechanical interfaces which allows it to be removed when not in use.
A range of optional support anvils and four-point conversion kits allow the fixtures to be configured to meet a wide range
of standards.
Specimens of the required size are supported by two
anvils attached to a base beam. Force is applied either at the centre (three point bend) or at two points between the supporting rollers (four point bend).
Deflection of the specimen can be measured using the
optional deflection measurement yoke and a suitable
extensometer.
