Because of the complexity of this multi-objective problem, the research employs an enhanced multi-objective particle swarm optimization technique with adaptive operator selection.

It encompasses classical models, including elastic beams, Maxwell fluids, Newtonian fluids, and the Oldroyd-B model, with validation confirmed through numerical examples. The approach uses a material point position vector to naturally derive the deformation gradient, effectively handling large axial strains, and focuses on tension, bending, and twisting while neglecting shear deformation to reduce computational costs. By pulling the evolution equation back to the reference configuration, evolution variables are explicitly expressed, avoiding solving nonlinear ordinary differential equations (ODEs), further minimizing computational load.

A novel equilibrium distribution function is introduced, derived directly from the macroscopic governing equations, ensuring fidelity to the underlying physics. Stability is inherently maintained across subcritical and supercritical regimes by dynamically adjusting the mesoscopic velocity via a Froude number–dependent parameter, eliminating the need for complex lattice modifications. This approach extends to the boundaries, where physically consistent conditions are implemented based on the new equilibrium function, allowing accurate mass and momentum exchange regardless of flow regime or rheology. Comprehensive validation against benchmark problems confirms the method's capability to capture stress-dependent behaviors of GNFs, including power-law and viscoplastic fluids. The dam-break case study illustrates how fluid rheology influences wave evolution and demonstrates the model's suitability for real-world studies.

Over the past decade multiderivative time-stepping have been increasingly used for the time-evolution hyperbolic PDEs, so that the strong stability properties of these methods have become important. In this work we review sufficient conditions for a two-derivative multistage method to preserve the strong stability properties of spatial discretizations in a forward Euler and different conditions on the second derivative. In particular we present the strong stability preserving theory for explicit and implicit two-derivative Runge–Kutta schemes, including a special condition on the second derivative under which these implicit methods may be unconditionally strong stability preserving. This special condition is natural for the stiff component of wide range of plasma physics problems, and can be useful in the context of strong stability preserving implicit-explicit multi-derivative Runge–Kutta schemes, where the time-step restriction is then independent of the stiff term. Finally, we present the strong stability preserving theory for implicit-explicit multi-derivative general linear methods, and some novel second and third order methods where the time-step restriction is independent of the stiff term.</div></div>","PeriodicalId":50980,"journal":{"name":"Applied Mathematical Modelling","volume":"149 ","pages":"Article 116270"},"PeriodicalIF":4.4,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, low-frequency attenuation has been achieved through the use of local resonators, which can be tuned to a specific low-frequency range by increasing their mass. To overcome this trade-off, we investigate the influence of two inertial amplifiers with distinct configurations: one with auxiliary masses connected to both beam and main mass and another with auxiliary masses suspended between the main mass and a fixed support. The transfer matrix method, combined with the spectral element method, is employed to analyze how design parameters influence the dispersion properties of each system. Our findings show that purposeful structural design of these inertial amplifiers can lead to as much as 50% broader attenuation bands across both high and low-frequency ranges. We also demonstrate near-coupling phenomena between local resonance and Bragg scattering mechanisms, which result in an ultra-wide low-frequency band gap.

Constitutive relations for the beam are derived, with the shear coefficient evaluated in an intrinsic and consistent manner. By neglecting the higher-order energy and applying the principle of virtual work, an asymptotic beam model is formulated, encompassing nonlinear equilibrium equations and boundary conditions, thus exemplifying an elegant framework for a beam body.

Within the UB formulation, the generalized Hoek-Brown (GHB) yield criterion is represented through a series of linear constraints and two conic constraints—specifically, a quadratic cone and a power cone. This allows the GHB yield criterion to be articulated in its original form without the need for smoothing the yield surface.
