Anti-plane interfacial waves in a square lattice

Networks and Heterogeneous Media, Journal Year: 2025, Volume and Issue: 20(1), P. 52 - 64

Published: Jan. 1, 2025

<p>Using the lattice dynamics approach, we discussed propagation of interfacial waves localized near interface in an infinite square lattice. The has been modeled as a single-particle layer material particles with masses and elastic bonds different from those bulk. In this structure there were anti-plane waves, i.e., that decayed exponentially distance interface. Such could be useful for determining properties vicinity We obtained equations motion analyzed corresponding dispersion relations steady-state solutions. Here, equation related circular frequency to wave number. addition, provided comparison derived within Gurtin-Murdoch surface elasticity. To do this, have used scaling law links continuum discrete models. Unlike model, model number was limited by first Brillouin zone, whereas it took range zero infinity. detailed parametric analysis given model. Finally, other models interfaces case discussed.</p>

Mathematics and Mechanics of Solids, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 6, 2025

In this study, the dynamic characteristics of a cantilevered Mindlin plate, partially or totally in contact with fluid on both sides, are examined using proposed hybrid isogeometric finite element – boundary framework. The interaction problem is divided into two parts through implementation linear hydroelasticity theory, allowing for independent treatment structural and problems. part analysis, thick plate modeled as first-order shear deformable by adopting Reissner–Mindlin material assumed to be homogeneous isotropic. resulting eigenvalue then solved method (IGAFEM). second assuming ideal incorporating vacuo conditions, fluid-structure effects determined (IGABEM) terms generalized added mass coefficients. Subsequently, parametric studies various thicknesses submergence depths conducted. analysis reveals that wet natural frequencies differ noticeably from their counterparts due presence free surface fluid. addition, effect radiated waves vibrating structure included mathematical model imposing linearized condition, frequency-dependent hydrodynamic damping numerical accuracy approach verified against commercial software ANSYS, showing favourable agreement predicted corresponding mode shapes.

Some Peculiarities of Using the Extended Finite Element Method in Modelling the Damage Behaviour of Fibre-Reinforced Composites

Materials, Journal Year: 2025, Volume and Issue: 18(8), P. 1787 - 1787

Published: April 14, 2025

The present study utilises the extended finite element method (XFEM) to model fibre-reinforced composites, with a focus on crack initiation and propagation. Silicon nitride-based ceramics were selected as material; they represent broad class of short fibre have received lot attention in recent decades. Some peculiarities when using XFEM, including its modifications, are discussed response applied external stresses, mainly viscoelastic range. Promising approaches recommended, which lead more accurate description these materials under operating conditions, focusing correct calculation macroscopic stress ahead propagating front. authors draw years experience material investigate possible improvements modifications XFEM.
