The 3D dynamic equations in elasticity for a thin transversely inhomogeneous plate are subject to asymptotic analysis over the low-frequency range. The leading and first order approximations are derived. The former is given by a biharmonic equation on the mid-plane generalizing the classical Kirchhoff equation for plate bending. A simple explicit formula for the effective bending stiffness is presented. The refined first order equation involves the same biharmonic operator, as the leading order ...

• Investigating buckling and post-buckling behavior of curved nanobeams. • Developing stress-driven nonlinear path. • Reporting geometrical limits of different type of nonlocal buckling. • Checking the relation between local and nonlocal buckling and also nonlinear limit loads. A nonlocal stress-driven model for geometrically nonlinear behavior of a shallow arch under radial pressure is presented. The analytical nonlinear equilibrium equation and also buckling equations by variational principles...

• We consider a thermoelastic medium with a deformable thread. • We derive models of heat conductive deformable threads. • We obtain property contribution tensors of thread-like inhomogeneities. The paper presents a novel approach for analysis of thermoelasticity problems for solids with deformable thread-like (wired, textile) inhomogeneities. It is proposed to model a thread-like inclusion with a spatial curve, with appropriate influence functions set on it. The mathematical models of heat cond...

In this paper we develop a three-dimensional constitutive model to describe the linear viscoelastic behavior of fluid-saturated porous solids. The proposed model is based on a representation of the solid free energy by equilibrium and non-equilibrium parts. Constitutive equations corresponding to a compressible solid matrix/phase and an incompressible solid matrix/phase are derived separately. For illustration, the theory is then applied to the classical Terzaghi's problem. To show the viscous e...

• Piezoelectric bimaterial with electrically conducting interface cracks is considered. • The number of cracks, their lengths and distances between each other can be arbitrary. • The problem of linear relationship is formulated and solved exactly. • All required electro-mechanical quantities along the interface are found analytically. • Simple formulas for the energy release rate at any crack tip are given. The plane problem of multiple collinear cracks between two piezoelectric semi-infinite sp...

• Novel triply periodic minimal surface-based photostrictive composites are designed and investigated. • Effective Multiphysics properties including elastic, thermal, piezoelectric, and pyroelectric are evaluated employing the finite element-based homogenization method. • At the same inclusion volume fraction, triply periodic minimal surface-based photostrictive composite produces better strain than conventional particle composite. This paper presents the novel triply periodic minimal surface (T...

This work is promoted to analyze the time-dependent behavior of composite panels. Furthermore, different curves and boundary conditions are also covered. The material properties for the composite panel are assumed to be vary continuously within z-direction. The effective material properties are estimated via Voigt’s micro-mechanical model by a modified-power law rule for arbitrary power index. The governing motion equations for the dynamics of imperfect panels are evaluated by rewriting the clas...

Surgical replacement of the diseased aortic valve consists in the implantation of a prosthetic heart valve (PHV), either biological or mechanical (BHV and MHV, respectively). Risks of complication have been linked to high levels of turbulence and consequent energy dissipation induced by the PHV. As helicity is an emergent feature in cardiovascular flows, deemed to impact blood flow organization, stability and the turbulent energy cascade, in this study the interplay between the production/decay ...

• Novel insightful analytical results for free transverse vibration of cracked nanobeams. • Derivation of nonlocal continuity conditions at the crack cross-sections. • Effects of crack location, crack length, and nonlocality are investigated. • Results are presented for higher modes of vibrations. • Model captures amplification/shielding effects of cracks on the frequencies. A nonlocal model is formulated to study the size-dependent free transverse vibrations of nanobeams with arbitrary numbers ...

• Kazakhstan is coming to the use of renewable energy sources. • The most affordable type of water supply are land-based water sources. • The lack of effective alternative pumping units affects the decrease in the competitiveness. This paper is aimed at studying the hydraulic ram (hydram) technology of water lifting from watercourses for water supply of pastures and irrigation of agricultural land with improving the technological parameters of a hydram pump – increasing energy indicators: hydrau...
