This study investigated the effect of heat-treated veneers on the physicomechanical properties and extended creep behavior of plywood using the stepped isostress method (SSM). The results revealed that the mechanical properties of plywood composed of fully and partially heat-treated veneers were not significantly different from those of the untreated plywood. In addition, the SSM was successfully applied to constructing the plywood creep master curves. The creep resistance of the heat-treated plywood surpassed that of the untreated plywood, especially the 5T₂₀₀ plywood, which also exhibited the lowest compliance values of 0.13, 0.14, and 0.15 GPa⁻¹ at 5, 10, and 20 years, respectively.

这项研究使用阶梯式等应力法（SSM）研究了经过热处理的贴面对胶合板的物理力学性能和扩展的蠕变行为的影响。结果表明，由完全和部分热处理的贴面组成的胶合板的机械性能与未处理的胶合板的机械性能没有显着差异。此外，SSM已成功应用于构建胶合板蠕变主曲线。热处理胶合板的抗蠕变性超过未处理胶合板，特别是5T ₂₀₀胶合板，其在5、10和20年时的柔韧性值最低，分别为0.13、0.14和0.15 GPa ^-1。
