Elastic Limit: Strength Properties of Living Trees
University Outreach Publication
<br /><br /> Small, finely tuned length measuring devices (elastometers) are placed on the tree trunk, especially around or over visible faults. The elastometers provide information to the assessor regarding impending fiber failures.<br /><br /> Elastometers measure the change in length of wood fibers closest to the stem surface just below the bark. When these measuring devices show an approach to the elastic limit, the cable pressure is gently and slowly released. The amount of force needed to approach the elastic limit will vary by each individual treeís structural condition. This assessment process can be used to estimate tree stability and to derive the wind load which could lead to catastrophic failure.<br /><br /> [SFR05-02]<br /><br /><br /><br />
