Abstract

This research explores the behavior of shear horizontal (SH) waves as they propagate through a unique size-dependent configuration where a stratum of fluid-saturated nonlocal fissured porous material overlays a substrate comprising nonlocal flexomagnetic material. The analysis focuses on how parabolic interfacial irregularity, nonlocality, and flexomagnetic effect jointly influence SH-wave behavior. By applying the Fourier transform alongside perturbation techniques, complex frequency relation is determined to describe SH-wave propagation across the irregular interface. The dispersion and damping properties of the waves are extracted from the real and imaginary components of the frequency relation. Key parameters, such as the flexomagnetic coefficient, shape of the interfacial irregularity, porosity, piezomagnetic properties, and nonlocality are evaluated for their impact on wave propagation. The results reveal that parabolic interfacial irregularity and flexomagnetic effects significantly modify SH-wave dispersion and damping characteristics. The study underscores the material-dependent nature of wave propagation in such complex layered systems and validates the proposed model through consistency with established wave propagation theories.

具有抛物界面不连续的孔弹性-柔性磁层状波导结构中sh波动力学模型

这项研究探索了剪切水平波（SH）的行为，因为它们通过一个独特的尺寸相关配置传播，其中流体饱和的非局部裂隙多孔材料层覆盖在由非局部柔性磁性材料组成的基底上。重点分析了抛物界面的不规则性、非局域性和柔性磁效应如何共同影响sh波行为。通过应用傅里叶变换和微扰技术，确定了复频率关系来描述sh波在不规则界面上的传播。从频率关系的实分量和虚分量中提取波的色散和阻尼特性。关键参数，如柔磁系数，界面形状不规则，孔隙度，压磁特性和非局域性，评估了它们对波传播的影响。结果表明，抛物界面的不均匀性和柔性磁效应显著地改变了sh波色散和阻尼特性。该研究强调了波在这种复杂的层状系统中传播的物质依赖性质，并通过与现有波传播理论的一致性验证了所提出的模型。

期刊介绍： Applied Mathematical Modelling focuses on research related to the mathematical modelling of engineering and environmental processes, manufacturing, and industrial systems. A significant emerging area of research activity involves multiphysics processes, and contributions in this area are particularly encouraged. This influential publication covers a wide spectrum of subjects including heat transfer, fluid mechanics, CFD, and transport phenomena; solid mechanics and mechanics of metals; electromagnets and MHD; reliability modelling and system optimization; finite volume, finite element, and boundary element procedures; modelling of inventory, industrial, manufacturing and logistics systems for viable decision making; civil engineering systems and structures; mineral and energy resources; relevant software engineering issues associated with CAD and CAE; and materials and metallurgical engineering. Applied Mathematical Modelling is primarily interested in papers developing increased insights into real-world problems through novel mathematical modelling, novel applications or a combination of these. Papers employing existing numerical techniques must demonstrate sufficient novelty in the solution of practical problems. Papers on fuzzy logic in decision-making or purely financial mathematics are normally not considered. Research on fractional differential equations, bifurcation, and numerical methods needs to include practical examples. Population dynamics must solve realistic scenarios. Papers in the area of logistics and business modelling should demonstrate meaningful managerial insight. Submissions with no real-world application will not be considered.
