摘要:
将木材干燥过程中的总应变分为自由干缩、瞬时弹性应变、黏弹性应变和机械吸附应变,并在此基础上建立了木材干燥应力模型。应用此模型,只需要在干燥过程中测量出木材的分层含水率和干缩率,便可较准确计算出木材干燥应力应变。通过对30 mm厚马尾松板材干燥过程中总应变实际测量值与模型计算值的比较,验证所建模型计算出的木材干燥应力应变具有较高的准确性。
Abstract:
Total strain of wood was divided into free shrinkage, instant elastic strain, viscoelastic strain and mechanosorptive strain. Drying stress model was established. From the model, the stress and strain could be accurately calculated according to the data of wood layered moisture content and the wood shrinkage. The model was verified by the measuring total strain of 30 mm Pinus massoniana board during drying.
