Application of Finite Element Method for Mechanical Characterization of Wood and Reconstituted Lignocellulosic-Based Composites – A Review

“…Wood deficits have increased interest in the use of non-woody lignocellulosic biomass as well as waste products from wood and non-woody materials for manufacturing composite products [4]. RLCs offer better flexibility than solid wood in terms of controllable properties during processing [17]. Consequently, if the process parameters are properly aligned, reconstituted composites could sometimes offer end products with physical or mechanical properties surpassing those from solid wood [17].…”

“…RLCs offer better flexibility than solid wood in terms of controllable properties during processing [17]. Consequently, if the process parameters are properly aligned, reconstituted composites could sometimes offer end products with physical or mechanical properties surpassing those from solid wood [17]. Currently, there is an upward shift in interest concerning the use of RLCs in building components like the roof, wall, and floor elements.…”

“…Applying computational techniques would alleviate such associated high-cost inputs by reducing the number of required experimental tests [14][15][16]. Moreover, the heterogeneity of lignocellulosic-based composites owing to the fusion of non-woody and woody materials with different physicochemical properties makes their characterization more challenging [2,17]. Thus, a resource-efficient approach such as computational modeling and simulation which offers the functionality to obtain a comprehensive understanding of localized and global behaviors of composites is desirable [2,18].…”

“…The application of the finite element method (FEM) is playing a significant role in this regard [14,19,20]. FEM is a robust numerical method applicable for the analysis of a wide range of engineering problems that include stress analysis, failure analysis, heat transfer, vibration analysis, fluid mechanics, electromagnetism, etc., to obtain approximate solutions [17,21,22]. The concept of FEM involves the subdivision of mathematical models for a region of interest into non-intersecting components in a process known as discretization to create finite elements of simpler geometries.…”

“…Thus, FEM has become a prominent method for analyzing solid structural systems to obtain an advanced understanding of their performance integrity [23,[26][27][28]. The obtained FEM solutions are validated in a cross-feed comparison with experimental outcomes [17,29]. The validated models are further applicable in broad and complex scenarios not easily explorable or unattainable by experimental measurements to enable sophisticated, speedy, and less-expensive investigations involving parametric study and design optimization [23,28,30].…”
