The wood veneer dried artificially before gluing for the manufacture of plywood generally suffers several damages (cracks, deformations), decreasing the competitiveness of the process and limiting the use of nervous species of wood. The proposed solution is to glue them at the green state. However, during the drying process, superficial and internal cracks are observed. These cracks appear when stresses due to the anisotropic shrinkage of the plywood exceed the mechanical strength of the wood material. In the present study, the response of a 3-ply plywood of Bete (Mansonia altissima) glued at the green state is simulated in order to evaluate these stresses and deformations during drying using a finite element method program. The numerical results and associated experimental data make it possible to better analyze and understand the mechanical behavior of the plywood during drying in order to look for reliable plywood through new process.

百特（Mansonia Altissima）种胶合板胶合板的干燥应力分析

在胶合制造胶合板之前人工干燥的木贴面通常会遭受多种损坏（破裂，变形），降低了工艺的竞争力，并限制了神经木的使用。提出的解决方案是将它们粘在绿色状态。然而，在干燥过程中，观察到表面和内部裂纹。当由于胶合板的各向异性收缩而产生的应力超过木材的机械强度时，就会出现这些裂纹。在本研究中，模拟了在绿色状态下胶合的三层Bete（Mansonia altissima）胶合板的响应，以便使用有限元方法程序评估干燥过程中的这些应力和变形。
