Abstract

This communication discusses the mathematical description of mechanical behaviour of bulk spruce wood chips under compression loading. The dependency between compressive force and deformation curve characteristic was fitted by reciprocal slope transformation (RST) and tangent curve (TC) methods. The mathematical model coefficients of both methods were respectively determined by the least squares method and Marquardt Levenberg approximation process, all applicable in MathCAD software. It is confirmed here that both methods can suitably be used for the illustration of deformation curve characteristic of bulk spruce wood chips.
