The aim of this work is to investigate the influence on wood stiffness of waviness and interconnection of cellulosic fibrils, an observed feature usually overlooked in micromechanical models. For that, a multi-scale model estimating the macroscopic behavior of wood is developed. This model integrates three different scales of wood structure: that of the cell wall, that of the cellular tissue and that of the growth ring. It relies on both numerical and analytical homogenization procedures to determine their effective behavior by defining at each scale a periodic representative volume element. Using this multi-scale model, it is shown that the influence of the oscillations and interconnections of the fibrils is significant for certain moduli at the macroscopic level (ring scale), such as the macroscopic shear moduli, while it can be neglected for others. Furthermore, although the effect of fibril crosslinks is quite strong for certain components of elastic behavior at the cell wall level, it loses its importance at the macroscopic level, especially for low-density wood. This trend can be explained by the anti-symmetric tilt of fibrils in adjacent cell walls. On the other hand, for denser woods where the interactions between adjacent cell walls are less dominant, or in the case of softened wood, the effect of fibril oscillations remains important.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"58 4","pages":"1555 - 1583"},"PeriodicalIF":3.1,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the measured creep compliance curves [<i>J</i><sub>TL</sub>(<i>t</i>)] were fitted using this Burger model, which is a typical model used to explain the creep behavior of wood. Furthermore, three modified Burger models with non-Newtonian dashpots were proposed to explain the measured data more accurately: model 1—only the dashpot in the permanent strain unit is non-Newtonian; model 2—both dashpots are non-Newtonian; and model 3—only the dashpot in the delayed elastic strain unit is non-Newtonian. The mean value of the coefficient of determination was highest for model 1. The number of specimens that could be fitted with a tolerance error of 0.1% was 43 out of 50 with the Burger model, 45 with model 1, 25 with model 2, and 45 with model 3. The Burger model exhibited large discrepancies between the theoretical and measured values, model 2 could not be used to explain several specimens, and model 3 exhibited a delayed elastic strain behavior that was inconsistent with the definition.

Prior knowledge is a technique that helps algorithms to adapt new data quickly, generalize better to new situations, and understand the results of learning models more effectively. In this study, the DMV (Dual-input MobileViT) model, which incorporates prior knowledge into the MobileViT model, is proposed to improve the recognition accuracy of few-shot samples of wood. The incorporation of texture features as prior knowledge in the deep learning model is motivated by their high discriminative capability in distinguishing various types of wood, supported by mature techniques and algorithms in digital image processing. This integration ultimately enhances the efficiency and accuracy of the recognition system. The effectiveness of incorporating texture features as structural prior knowledge into the model is demonstrated by a final training accuracy of 97.8% and a testing accuracy of 92%. To enhance robustness, the texture loss is weighted with the original loss function, creating a new loss function applied to the model. Extensive experiments have shown promising results, demonstrating the advantages of the proposed approach.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"58 4","pages":"1517 - 1533"},"PeriodicalIF":3.1,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
