Numerical modeling for adjustment of the equivalent moduli of elasticity of OSB layers estimated from experimental flexural rigidity

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

“…Besides, linearization status should also be considered a major influential factor. In modeling reconstituted wood-based composites, result variation due to material non-linearity is surmountable by applying multi-linear function adjustments for the stress-strain relationship as reported by Soriano et al [5]. The authors suggested consideration of the elastic-linear behavior up to 60% of the ultimate stress.…”

“…In the last two decades, composite development using reconstituted fibers and particles from wood and plant origin for non-structural and structural components in buildings has exponentially increased. 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.…”

“…Some of these elastic constants have been reported in the literature for various hardwood and softwood species [16,24]. Some of the major advantages of FEM application stem from the fact that the FEA procedure enables consideration of the individual peculiarities of the components or layers of a composite [5] and non-destructive manipulation of geometrical configurations to obtain predictive behavior in response to applied stress [25]. 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].…”

Sandwich panel of oriented particles with unconventional and waste materials

“…Some recent studies have investigated OSB panels produced with balsa wood residue from reforestation, agglomerated with organic resin (BARBIRATO et al, 2019a(BARBIRATO et al, , 2018EDUARDO et al, 2021;HELLMEISTER et al, 2021;LOPES JUNIOR et al, 2021;SORIANO et al, 2021). All these studies, however, used resin contents higher than 11%.…”
