Evaluating Strength Properties of Pinus radiata from Ultrasonic Measurements on
Increment Cores
Summary
Static bending tests were conducted on seasoned plantation-grown Pinus radiata D. Don specimens.
After the tests, core specimens of two different sizes (ø 10 × 30 mm and ø 10 × 20 mm) and small clear
specimens of 20 × 20 × 60 mm were taken from intact zones of the post-test specimens. Ultrasonic
measurements were made on the core specimens and the apparent longitudinal dynamic modulus of elasticity
(ELD) calculated. The small clear specimens were subjected to parallel-to-grain compression tests.
The coefficient of determination was 0.85 between the static bending modulus of elasticity and ELD, 0.62
between the modulus of rupture and ELD, and 0.56 between the maximum crushing strength and ELD.
