摘要
This paper had developed a theoretical mathematics model of wood drying stress-strain using mathematical and physical theories and taking moisture content (MC) and ratio of every layer into consideration as explicit parameters,predicted the development of stress-strain using MATLAB software,and analyzed the effect of MC and ratio of every layer. The results showed that on the condition of making the basic parameters set,the charts plotted by MATLAB software reflected the effect of MC and ratio of every layer. Total strain changed linearly with MC. The model could be applied to analyze the drying characters of a specimen with symmetric properties through the thickness.
