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

“…The tremendous increase is attributable to significant efforts geared toward the valorization of lignocellulosic waste streams that include lesser-use small dimension wood [4], wastes from wood processing [1,5], and agricultural residues such as flax and hemp fibers [6][7][8][9][10][11]. Likewise, the desire for products with a low carbon footprint towards environmental sustainability and a green economy [8], and the need to replace petroleum-based products with renewable and biodegradable materials as noted by several authors [6,9,[12][13][14] continue to promote the exploration of lignocellulosic biomass such as hemp fiber [6,8,9,12,13] and wood [14] for the manufacturing of bio-based composites. However, to enhance the emerging growth and industry acceptance of wood and lignocellulosic-based composites, the approach by which these composites' characteristics are evaluated must equally be advanced to meet contemporary expectations of a rapid and broad performance evaluation and optimization process.…”

“…Muzel et al [2] pointed out the need for technological advancement in the evaluation and optimization of composite properties. El Houjeyri et al [14] and O'Loinsigh et al [15] noted the multi-scenarios of various parameters such as material and geometrical factors involved in experimental programs to determine composite properties. Conducting these comprehensive experimental programs involves high resource costs such as materials and time that are sometimes beyond reasonable and efficiently attainable levels by direct physical testing.…”

“…Conducting these comprehensive experimental programs involves high resource costs such as materials and time that are sometimes beyond reasonable and efficiently attainable levels by direct physical testing. 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].…”

“…The approach of computational modeling and process simulation as a non-destructive and resource-efficient method for predicting the behavior of wood and other lignocellulosic-based composites is gaining more attention. 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].…”

Method of Calculation for Walls of Vertical Squared Timber

“…The elements of wooden walls are connected not only with metal but also with wooden fasteners. Thermo-mechanically compressed wood dowels were suggested as a joint element as an alternative to glue and metal fasteners (El Houjeyri et al, 2021).…”
