PLYWOOD Screw Holding Test

Plywood Static Bending Strength Test

Find out what engineers mean by the words “strength and stiffness” and watch a bending test on a wooden joist.  We do lots of tests like this because we need to calibrate our non-destructive methods of measurement.

Wood is commonly tested for flexural strength. This video shows a 2 x 4 supported on each end by supports. A universal testing machine is used to apply force to the middle of the 2 x 4 until failure occurs. Load and position data are acquired and plotted. By taking the geometry of the 2 x 4 into account as …

The maximum static bending strength of SPC flooring is 22.607MPa, the maximum force is 22.54kg, the depression deformity is 4.817mm, and the bending elastic modulus is 7507.33MPa, with good resilience.

Modulus of rupture (MOR) and modulus of elasticity (MOE) are the most important mechanical properties of load-bearing plywood applications  .
