Static strength characteristics (MOR and MOE) of Australian Pinus ponderosa wood from plantation: A comparison of green, dry and re-wet specimens: A technical note

Abstract

The aim of this preliminary study is to determine the mechanical characteristics of Pinus ponderosa from mature-age Australian plantation (80 years old) in relation to three parameters: modulus of rupture and modulus of elasticity in bending, and density. The strength test was carried out on two groups of heartwood specimens: juvenile wood and mature wood. The specimens were studied in green state, dry (kiln dried at 12 % moisture content) and re-saturated (50-60 % moisture content) state. The comparison of the P. ponderosa' modulus of elasticity and modulus of rupture average values with P. radiata and P. loblolly values from Australia and New Zealand was done so that the aptitude of P. pon..
