Boltzmann principle of superposition in the theory of wood creep for deformations in time

Abstract

A number of theoretical orientations can be distinguished in the field of wood creep study. The first orientation includes models based on different combinations of the simplest linear models: Hooke model of elastic body, viscous element of Newton, element of dry friction of Coulomb. The second orientation is based on the parallel connection of the elastic element with the viscous element. In the third orientation the elastic and viscous element are arranged sequentially. In the fourth orientation the Boltzmann theory of elastic inheritance is used. This article considers the feasibility and practicability of the study of wood creep within a framework of the latter of these orientations. The evidence of the erroneous of using this principle is given.
