Abstract

Mechanosorptive creep strain (MCS) is a strain component that can dominate the overall deformation behavior of wood components under load and changing moisture. In this work, the MCS behavior of Norway spruce (Picea abies) tissues is investigated in the anatomical directions perpendicular to grain and different loading degrees (LD). The MCS is evaluated through a strain decomposition of the total strain, which is determined using a computer-controlled digital image correlation (DIC) system. It is shown that the common assumption of a scalar relation between mechanosorptive creep compliance (MCC) and the orthotropic, moisture-dependent elastic one is questioned by experiments.

挪威云杉在垂直于颗粒的组织尺度上的机械吸附蠕变。

机械吸附蠕变应变（MCS）是一种能够主导木材构件在载荷和水分变化作用下整体变形行为的应变分量。本文研究了挪威云杉（Picea abies）组织在垂直于晶粒的解剖方向和不同加载程度（LD）下的MCS行为。MCS是通过总应变的应变分解来评估的，总应变是由计算机控制的数字图像相关（DIC）系统确定的。实验表明，力学吸附蠕变柔度（MCC）与正交各向异性、水分相关的弹性蠕变柔度之间的标量关系的普遍假设受到质疑。
