Abstract
The strength in tension perpendicular to the grain is known to
decrease with an increase in the stressed volume. Usually this
size effect is explained on a stochastic basis, that is an
explanation relying on an increased probability of encountering a
strength reducing flaw when the volume of the material under
stress is increased. This paper presents a small experimental
investigation on specimens with well defined structural
orientation of the material. The experiments exhibit a larger size
effect than expected and furthermore the data and the nature of
the failures encountered suggest that the size effect can be
explained on a deterministic basis. Arguments for such a simple
deterministic explanation of size effect is found in finite
element modelling using the orthotropic stiffness characteristics
in the transverse plane of wood.
