Abstract

This set of papers sums up the results of an extensive project to quantify primarily the creep characteristics but also other deformation properties of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) wood under conditions relevant in the high temperature drying process. This paper reports on the experimental results obtained concerning creep in tension under constant conditions, primarily in wet (saturated, green) state at temperatures 95 °C±125 °C. The results are compared to some other researchers' measurements in a trial of the applicability of the time±temperature±moisture-content superposition
principle. Based on these results, a master curve is determined by curvefitting for use in practical calculation of the elastic and viscoelastic compliance in different conditions.
