Remarks on orthotropic elastic models applied to wood
Wood is generally considered an anisotropic material. In terms of engineering elastic models, wood is usually treated as an orthotropic material. This paper presents an analysis of two principal anisotropic elastic models ...
Mensuração do comprimento das fibras para a determinação da madeira juvenil em Eucalyptus citriodora
The juvenile wood has peculiar characteristics from the anatomical structure and physical-mechanical properties, considering these aspects the knowledge of the wood is essential for wood adequate utilization. The aim of ...
Influence of wood treatments on mechanical properties of wood-cement composites and of Populus Euroamericana wood fibers
Woodecement composites are interesting materials for structural and isolation purposes. Dimensional stability, economic factors and resistance to environmental degradation are features that can be exploited for housing ...
