Abstract:

Numerical models for wood fracture and failure are commonly based on the finite element method. Most of these models originate from general theoretical considerations for other materials. This limits their usefulness because no amount of complexity in a model can substitute for lack of an appropriate representation of the physical mechanisms involved. As for other materials, wood fracture and failure models always require some degree of experimental calibration, which can introduce ambiguity into numerical predictions because at present there is a high degree of inconsistency in test methods. This paper explores avenues toward achieving models for wood fracture that are both appropriate and robust.
