Changes of Mechanical Properties of Wood under an Unstable State by Heating or Cooling
stress relaxation unstable state temperature history amount of fluidity
2009/3/6
In this paper stress relaxation of water-swollen wood was discussed with two conditions of temperature change, i.e. 1) specimens at 20°C were heated rapidly to 30-80°C, and 2) specimens at 30-80°C wer...
Relationships between Pressure in a Closed Space and Set Recovery of Compressive Deformation of Wood Using a Closed Heating System
