Abstract

The relationship between the mechanical properties of anisotropic materials and their thermophysical characteristics was experimentally revealed using the example of Scots pine (Pınus sylvéstris L) wood. By measuring the hardness and principal components of the thermal diffusivity tensor, on three sections (normal to the fibers, tangential, and radial) at different wood moisture content, it has been shown that this relationship can be described by linear functions. This makes it possible to carry out an express assessment of the mechanical properties of anisotropic materials, which normally require labor- and material-intensive destructive tests, by means of contactless nondestructive determination of their thermophysical characteristics using the method of dynamic thermography.

以松木为例的各向异性材料的力学性能与其热物理特性的关系

摘要

各向异性材料的机械性能和它们的热物理特性之间的关系进行了实验使用透露欧洲赤松的例子（松sylvéstri木材。S L）。通过在木材含水量不同的三个部分（垂直于纤维，切向和径向）上测量热扩散张量的硬度和主要成分，已表明可以用线性函数描述这种关系。这使得可以通过动态热成像方法通过非接触非破坏性确定其热物理特性，来对各向异性材料的机械性能进行明确的评估，而各向异性材料通常需要劳动和材料密集的破坏性测试。
