3. Introduction
Major issues related to strength prediction of bonded joints
involving timber adherends
- Timber has to be considered as a brittle material
4. Timber mech props have a rel. high variability 5. Stresses in
the bonded splice are characterized by high peaks, especially both
y and xyAs a result
- Any stress based prediction method is deemed to fail
