Classical, first- and third-order shear deformation theories are applied to the formulation. The developed Trefftz-based method creates exclusive basis functions capable of satisfying the equilibrium by means of weighted residual imposition of the equation, thus enhancing the accuracy of the results. The solution function has complete continuity, which paces up its convergence. The integration is performed analytically independent of the domain shape, thus removing the need for numerical quadrature throughout the solution procedure. For more versatility, a domain decomposition approach is developed with up-to-desired order of continuity, leading to considerable mesh reduction compared with mesh-based methods. Derived in one step, the overall multi-domain solution does not need repetitive approaches to converge. Because of independent satisfaction of the equilibrium by the basis functions, the boundary and continuity conditions may be imposed in point-wise style, removing the cumbersome boundary integration. Simultaneous in-plane and transverse graded variation of the material properties and porosity is considered. Verification of new results by 3D finite element solution reveals high accuracy and efficiency of the method. Comprehensive parametric study is also performed for FG and BDFG porous plates with various distributions and variable thickness.</p></div>","PeriodicalId":477,"journal":{"name":"Archive of Applied Mechanics","volume":"95 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key findings show that increasing the strain rate increases the dynamic strength while decreasing the average fragment size. Significantly, rock strength is reduced when double-scale crack interactions are considered compared to single-scale analyses.

Indeed, early numerical solutions have found various instabilities or zig-zag in the predicted shear tractions, and more refined friction laws have been suggested to avoid these complications. With a “Winkler” model, which is used in the FASTSIM type of algorithms of Kalker, the relative velocity in the slip area develops a non-physical jump, which is reflected also in friction coefficient and shear tractions. This is due to the simplification of the elastic deformation with a purely “local” model. However, given the Winkler approximation is a strong one, it is suggested to avoid the full solution, and we develop instead an approximation which assumes a constant friction coefficient in the slip area, which leads to a nonlinear algebraic equation to find this average friction coefficient. This permits a quite simple solution which shows all the expected trends in terms of creepage vs tangential force ratio, and hence can be useful for estimating the effect of rate-dependency of friction.

The mechanical properties of the nanocomposite are assessed using a modified Halpin–Tsai micromechanics model, which incorporates considerations of agglomeration and waviness of CNTs within the matrix. Subsequently, the enhanced nanocomposite matrix is integrated with unidirectional and oriented CFs.

It is found that increasing the CNT weight fraction enhances natural frequencies, with the introduction of CFs further amplifying this effect. Among the CNT patterns, CNT-O pattern is observed to have the most significant impact, while CNT-X pattern shows the least. Under severe agglomeration and waviness, influence of waviness becomes dominant, leading to a decrease in natural frequency for CNT weight fractions exceeding 1%.

In the steady-state regime, the reaction forces exerted by the foundation on the beam are assumed to exhibit periodicity, repeating as the moving loads traverse one complete period of the foundation. This periodicity condition is analogous to that observed in beams supported by discrete periodic supports. By employing the Fourier transform, the governing dynamic equation of the beam, combined with the imposed periodicity condition, leads to a linear differential equation with a periodic coefficient. To determine the system’s response, Floquet’s theorem is utilized, providing a rigorous mathematical framework for analysing the stability and dynamics of the beam.

Firstly, the system of equation for the problem of a harmonic plane wave propagating in a transversely isotropic piezoelectric medium is briefly stated following the weakly nonlocal theory. This theory ensures the well-posedness of the plane wave problems and provides the exact expressions for the characteristic equation and the nonlocal eigenvectors of a harmonic plane wave in explicit forms. Secondly, the problem of reflection and transmission of an incident qP wave at an imperfect interface between two half-spaces is considered. The imperfect interface includes both mechanically and dielectrically weakly imperfect properties. The imperfect nonlocal boundary conditions are used for three sets of waves, namely the quasi-longitudinal wave (qP), the quasi-transverse wave (qSV) and the electroacoustic wave (EA) to obtain the amplitude ratios of the reflection/transmission waves to the incident wave as well as the energy flux ratios. Next, some numerical results are computed to graphically illustrate the effect of nonlocal property and the effect of imperfect interface on the energy flux ratios of the reflection/transmission waves. It is shown that nonlocal property has a considerable effect for incident waves of short wavelength. Finally, a potential application of the present study to estimate the state of imperfect interface is illustrated by some examples of inverse problem using information of energy flux ratios of transmission qP wave.
