In recent decades, significant effort has been put into designing ventricular assist devices to treat heart conditions, as heart transplantation can benefit only a small number of patients. These pumps are usually employed to assist the heart …

The existence of backlash causes de-meshing and reverse impact in the gear system, and the influence of the working lubrication conditions of the gear on the dynamics is ignored. This study focused on the impact of the coupling characteristics of …

Shaft-gear systems are integral parts of industry. To analyze these systems using an existing classical method, one should first write the static equilibrium and compatibility equations and then solve these equations simultaneously, which is …

Since a decade, Computational Fluid Dynamics (CFD) simulations for Wind Engineering (WE) on large-scale environments became a norm. Meso- $$\gamma$$ γ scales and microscale can be characterized by a large number of structures as well as complex …

The structure of natural biomaterials such as mollusk shells, conch shells, fish scales, and sea turtles, serves as a basis for inspiration in this study. We designed two composites with octahedral structures which can preferentially hinder the …

This paper presents a semi-analytic solution for the continued quasi-static compression of a thin rigid/plastic layer between two rigid, parallel rough plates. The constitutive equations of isotropic material postulate that the shear yield stress …

There is a clear and compelling need to correctly write the equations of motion of structures in order to adequately describe their dynamics. Two routes, indeed very different from a philosophical standpoint, can be used in classical mechanics to …

In the thin airfoil theory, the camber line and the thickness distribution of general airfoils are mainly extracted by a linear combination of the upper and lower surfaces, giving rise to geometric distortions at the leading edge. Furthermore …

We consider a flow of non-Newtonian incompressible heat conducting fluids with dissipative heating. Such system can be obtained by scaling the classical Navier–Stokes–Fourier problem. As one possible singular limit may be obtained the so-called …

Owing to the high fluid content, most incompressible soft structures typically exhibit viscosity, which has a significant influence on wave characteristics, especially attenuation. Meanwhile, they are inevitably prestressed owing to the …

In this work, the numerical analysis of the modified Reynolds equation is compared. The difference between the two analyses is the porous media flow equation; the first considers the Darcy model, and the other the Darcy–Forchheimer model. The …

In recent years, deep reinforcement learning has emerged as a technique to solve closed-loop flow control problems. Employing simulation-based environments in reinforcement learning enables a priori end-to-end optimization of the control system …

Designers are continuously searching for materials or meta-structures, also inspired by nature, that exhibit favourable strength-to-weight ratios, substantial heat transfer capabilities, and efficient energy absorption. One particular example …

A variational model has been developed to investigate the coupled thermo-mechanical response of a three-dimensional continuum. The linear Partial Differential Equations (PDEs) of this problem are already well-known in the literature. However, in …

Starting from a classical thermodynamic approach, we derive rate-type equations to describe the behavior of heat flow in deformable media. Constitutive equations are defined in the material (Lagrangian) description where the standard time …

The paper deals with the statement and the application of the entropy principle, through the Clausius–Duhem inequality, in continuum physics. The conceptual role is taken from the Coleman–Noll paper of 1963 thus leading to the physical …

Computational fluid dynamics (CFD) has been developing rapidly during the last decades for usage in wind engineering. OpenFOAM plays a big role in this respect since it is a reliable open-source tool frequently used in state-of-the-art …

Additive manufacturing enables the production of lighter, more robust components with intricate features like lattice structures. However, since the mechanical behaviour of lattice structures is not fully characterized, the application of such …

The demand for adaptable structures is steadily increasing in contemporary architectural practice. Deployable structures, characterized by their flexibility and versatility, offer innovative solutions across demanding engineering and architectural …

Computer simulations offer invaluable insights into fluid-structure interaction phenomena, increasing our understanding of complex behaviors within fluid flows and enabling predictions of consequential effects. This paper explores flapping wing …
