Estimating spatial changes in acoustic velocity in felled Douglas-fir stems

Creator:

Dowding, Bodie

Abstract:

To compete with other building materials, the wood products industry must find a way to increase value and lower costs. Wood stiffness is important for most wood uses. Value can be increased and costs can be lowered by sorting logs for stiffness in the woods using acoustic devices mounted on...

Using Acoustic Measurements and Inventory Data to Estimate Stiffness in Standing Douglas-Fir Trees

Creator:

Delgado Trejo, Jorge Luis

Abstract:

Total US lumber production in 2011 was 77.9 million cubic meters. Its primary use was for housing and construction. There is a growing concern that the structural properties for wood are being reduced as trees are harvested at much younger ages as the wood supply shifts from older to younger...
