Summary
The mechanics of growth stress generation in a tissue of developing wood cells is studied by means of a continuum-mechanical model which assumes that the stresses which accumulate in the cells are induced by growth strains in the newly formed cell wall increments as they are laid down. The feasibility of the model is examined by using cell parameters both anatomical and physical to predict the variation of growth stresses with microfibril angle. In particular the measured change from tensile to compressive stresses with increasing microfibril angle for conifers is compared with the results predicted by the model.
