Abstract
A test specimen and equation are demonstrated to measure critical Mode II stress-intensity factor KIIc for wood. Knowledge of this critical material property is necessary for predicting crack propagation loads and, specifically, split propagation loads in split wood beams. Results for the specimen with two different notches reveal a difference in coefficient of variation of KIIc of a factor of two.
