Each of these models accounts to the presence of interfacial imperfection between stratum-substrate configuration. Variable separable approach is employed to establish dispersion relations corresponding to aforementioned models in view of associated magneto-electric boundary and continuity conditions. The established dispersion relations, when deduced as special case, concur well with the results existing in literature. With aid of numerical computation, effects of affecting parameters, viz. magneto-mechanical and electro-mechanical coupling parameters, spring interface parameters, membrane interface density parameter, mass loading sensitivity and wave number, on phase velocity of LT wave are traced out graphically. The computational results manifest prominent influence of interfacial imperfections on the attributes of propagating wave. A comparative analysis for dispersion curves with and without mass loading and for sensitivity due to mass loading pertaining to considered models is also demonstrated. The outgrowth of this study may be applied in the design of surface acoustic wave devices (SAWD) such as Love wave sensor.</div></div>","PeriodicalId":14053,"journal":{"name":"International Journal of Engineering Science","volume":"209 ","pages":"Article 104225"},"PeriodicalIF":5.7,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we unveil that the intrinsic length obeys a gradient law determined by the configuration of the functionally graded lattices. Based on the unveiled gradient law, a configuration-driven nonlocal model is developed to predict the size-dependent mechanical behavior of axially graded lattices. An offline dataset of the intrinsic length is constructed based on the gradient law and the high-throughput simulations. With the help of the offline dataset, the configuration-driven nonlocal model can be used to accurately and efficiently analyze the mechanical behaviors of the functionally graded lattices online. The configuration-driven nonlocal model improves the accuracy of the classic micromechanics homogenization method and reduces the computational cost of the high-resolution finite element method. The developed model not only guides the design of functionally graded lattices but also offers an effective multiscale approach for their performance prediction.</div></div>","PeriodicalId":14053,"journal":{"name":"International Journal of Engineering Science","volume":"209 ","pages":"Article 104222"},"PeriodicalIF":5.7,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143378434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were efforts to describe adaptation in trabecular bone with mathematical models regulating resorption and formation activities as a function of mechanical stimuli. In this paper, an approach to optimise parameters of a bone-adaptation model is proposed and investigated, and the simulation results of trabecular-bone adaptation are quantitatively compared with high-resolution peripheral quantitative computed tomography (HR-pQCT) scans of a distal tibia in a participant following six months of physiological loading. For this purpose, finite-element models were developed from baseline scans of the participant's trabecular bone and used as an initial domain to run simulations regulated by the bone-adaptation model implemented in a Fortran subroutine. The simulated results were element-by-element compared with the corresponding models from follow-up HR-pQCT scans.

In the boundary conditions representing physiological loading, they predicted higher bone resorption rate in the inner regions of distal tibia than in the outer regions, intensified bone resorption in the anterior-inner, medial-inner and medial-outer regions, higher bone formation rate in the outer regions of distal tibia than in the inner regions, and intensified bone formation in the lateral-outer region.</div></div>","PeriodicalId":14053,"journal":{"name":"International Journal of Engineering Science","volume":"209 ","pages":"Article 104209"},"PeriodicalIF":5.7,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143133825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, exemplified by fibre-reinforced laminates, the asymptotic behaviour of three-dimensional full-resolution models of microstructural plates is studied. Without containing any phenomenological parameters but merely the information about the isotropic constituting materials and the microstructural geometry, the derived (leading-order) asymptotic plate model is able, not only to reproduce the quantities indexing the homogenised properties of a microstructural plate, such as its stiffness coefficients and vibration modes, but also to predict the locally heterogeneous stress distribution. For fibre-reinforced laminates, the internal stress distribution can be calculated in a semi-analytical manner, and the relative error in stress prediction is shown to be lower than 8.5% for an arbitrarily oriented laminate bearing a slenderness of 0.08. The predictability of the introduced asymptotic plate model is also demonstrated over methods based on the concept of representative volume.</div></div>","PeriodicalId":14053,"journal":{"name":"International Journal of Engineering Science","volume":"208 ","pages":"Article 104199"},"PeriodicalIF":5.7,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
