Abstract
This review primarily describes nondestructive evaluation (NDE) work at Mississippi State University during the 2005–2020 time interval. Overall, NDE is becoming increasingly important as a means of maximizing and optimizing the value (economic, engineering, utilitarian, etc.) of every tree that comes from the forest. For the most part, it focuses on southern pine structural lumber, but other species such as red pine, spruce, Douglas fir, red oak, and white oak and other products such as engineered composites, mass timber, non-structural lumber, and others are included where appropriate. Much of the work has been completed in conjunction with the U.S. Department of Agriculture, Forest Service, Forest Products Laboratory as well as the Agricultural Research Service with the overall intent of improving lumber and wood products standards and valuation. To increase the future impacts and adoption of this NDE-related work, wherever possible graduate students have contributed to the research. As such, a stream of trained professionals is a secondary output of these works though it is not specifically detailed herein.
Highlights
In an ongoing effort to enhance forest sustainability and utilization, nondestructive evaluation (NDE) research is permeating into an increasing number of applications
Anderson et al [4] found that modulus of elasticity (MOE) and/or modulus of rupture (MOR) may change at a given mill over time
To broaden the impacts and implications of this work, these analytical techniques related to fitting statistical distributions to MOR and MOE have been applied to mill run spruce and red pine lumber populations by Anderson et al [11]
Summary
In an ongoing effort to enhance forest sustainability and utilization, nondestructive evaluation (NDE) research is permeating into an increasing number of applications. At this stage, this type of research is often more applied than basic. For structural evaluation of sawn products, one begins with a notion or idea (generally based on mechanical testing) of the strength and stiffness values of clear wood. For strength, both the mean and the distribution are examined in an effort to estimate the fifth percentile. The federal and state input and interest has assured that the work maintains broad interest and influence across the state, region, and national levels
