Instances of different failure modes experienced (n) and associated average diameter ratios (μ) of control and bark-included forks subjected to tensile testing.
| Specimen type | Branch failure | Type I failure | Type II failure |
|---|---|---|---|
| Control | n = 9 | n = 53 | n = 73 |
| μ = 76% | μ = 74% | μ = 86% | |
| Bark-included | n = 6 | n = 29 | n = 71 |
| junctions | μ = 66% | μ = 76% | μ = 86% |
