Estimating a Relationship Between Different Destructive Tests on Timber
研究木材弯曲强度与拉伸强度之间的关系，由于两者无法同时测量，利用弹性模量等非破坏性测试信息来预测拉伸强度。
SUMMARY In the experiments dealing with specimens of timber, tests conducted to measure bending strength, B, or tension strength, T, are destructive so that one can measure either B or T but not both. However, tests conducted for measuring the modulus of elasticity, E, are not destructive; thus one can only measure (E and T) or (E and B) jointly. A specific design of experiment used to determine relationships between B and T is presented and studied in detail. Construction and estimation of a relationship for predicting T using information on E and partial information on 8 is also considered.
