Summary

Characteristic features of wood deformation under loading at changing moisture contents (temperature) are discussed on the basis of results from rheological tests with hardwood. General laws of deformation in wood as a result of various cyclic effects of loading as well as of temperature and moisture content have been established. These laws have been used to solve the problem of the plane stress state in lumber when dried by using the “method of finite elements”. To control internal stresses and for an effective drying process, it is suggested that differential shrinkage should be measured, i.e. the difference between the displacements of points on Both verges of the board's edge and in the centre of the edge.
