IV. Working Principle

During compression testing, the wood specimen is installed in the fixture and compressed by a universal testing machine. Within the proportional limit of the material, the relationship between applied stress and corresponding strain is measured.

The modulus of elasticity is calculated according to:

E = Stress / Strain

where:

E = Modulus of Elasticity (MOE)

Stress = Applied compressive load per unit area

Strain = Deformation ratio of the specimen

The fixture ensures stable specimen positioning and accurate deformation measurement during the compression process, helping obtain reliable test results.

V. Why Choose This Timber Compression Test Fixture?

Compared with general compression testing accessories, this fixture provides a dedicated solution for timber mechanical testing. It improves specimen positioning accuracy, simplifies test preparation, and ensures reliable deformation measurement when determining the compression modulus of elasticity of wood.
