Critical Force for Buckling Tree Stems
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=410
Tree strength and stiffness can resist significant forces and not fail. A large proportion of this strength lies with the thickness (diameter) of the stem. Stem buckling occurs when an exerted force begins and continues to bend the stem beyond recovery.

Estimating Weights of Branch Segments
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=414
Estimating the forces and loads applied in tree systems requires the weight of different parts and portions be determined. One of the most difficult measures to estimate is green xylem weight in branches. Wood weight can be precisely and accurately deter…

Off-centered Cavity Impact on Stem Strength
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=404
One aspect of hollow stem assessments for strength loss involves various forms of stem cross-sectional area damage. One of the scenarios often cited but seldom determined is a stem which has a cavity of a given diameter, but the cavity is not centered in t…

Open Cavity Impact on Stem Strength
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=403
Assessing tree strength is a complex process. The dynamic nature of how trees resist forces include soil, tree, and environmental components. Cavities signify a common loss of cross-sectional area and associated strength in stems. Small cavities centered

Sway Frequency in Tree Stems
http://www.forestry.uga.edu/warnell/service/library/index.php3?docID=408
Assessing potential risks in trees is difficult because of the complex and chaotic nature of gauging tree failures. Tree movements in the wind, and the interactions between/within tree structure and soils, assure a multitude of forces, loads, and stress c…
