Computer simulation was conducted to assess the effect of the rate of drying on stress in wood during drying. Numerical calculations for the simulation were carried out with an electronic computer FACOM 270-20/30. Examples of the flow chart and FORTRAN programs used are shown in the text where we assumed that the stress follows the integro-differential equation derived previously, and that the unknown factors in the equation can be decided as before2). However, six different levels in the rate of drying were assumed in this report.The results obtained are summarized as follows:(1) The increase in the rate of drying promotes the stress development.(2) The relation between the stress development and the moisture content does not depend so much on the rate of drying.(3) The maximum stress decreases nearly inversely with the increase of necessary drying time.(4) The maximum tensile stress appears somewhat earlier than the maximum moisture gradient.(5) The inelastic strain due to creep has a tendency to restrict the stress development and this tendency increases with decreasing the rate of drying.From these results, it is clear that the computer simulation provides many useful informations on the stress in wood during drying.
