Summary

Naturally-occurring growth stress patterns in timber are modified by cutting. Stresses in cut timber may cause destructive cracks and splits. This research uses a three-dimensional finite element method to study how non-axisymmetric cuts affect the stress pattern. The results show that some oblique cuts reduce high stresses near the pith. Experimental work supports the calculations.
