Design of multi-material isotropic auxetic microlattices with zero thermal expansion

open access: yesMaterials & Design, 2022
Auxetic metamaterials are a type of mechanical metamaterials possessing negative Poisson’s ratios and displaying counter-intuitive deformation behavior, which are useful for a range of potential applications.

Elastic deformation in ceria nanorods via a fluorite-to-rutile phase transition [PDF]

open access: yes, 2010
Atomistic simulations reveal that ceria nanorods, under uniaxial tension, can accommodate over 6% elastic deformation. Moreover, a reversible fluorite-to- rutile phase change occurs above 6% strain for a ceria nanorod that extends along [110]. We also

Dynamic Thermal Modeling of the Normal and Tumorous Breast under Elastic Deformation [PDF]

open access: yes, 2008
To quantify the complex relationships between (1) the temperature, and temperature differences, on the surface of the breast as recorded by infrared thermal imaging and (2) the underlying physiological and pathological factors, we have developed a dynamic finite element method for comprehensive modeling of both the thermal and elastic properties of ...

Analysis of functionally graded sandwich plates using a new first-order shear deformation theory [PDF]

open access: yes, 2014
In this paper, a new first-order shear deformation theory is presented for functionally graded sandwich plates composed of functionally graded face sheets and an isotropic homogeneous core. By making a further assumption to the existing first-order shear

Linear matching method for design limits in plasticity [PDF]

open access: yes, 2010
In this paper a state-of-the-art numerical method is discussed for the evaluation of the shakedown and ratchet limits for an elastic-perfectly plastic body subjected to cyclic thermal and mechanical load history. The limit load or collapse load, i.e. the

Analyses of thermal and elastic deformations of honing head.

open access: yesJournal of the Japan Society for Precision Engineering, 1990
This paper presents the deformation characteristics of honing head in order to improve the accuracy in honed hole diameter of in-process automatic sizing in honing. Thermal deformation by the warmed honing oil or by the heat generated during machining is experimentally examined.

On large bending deformations of transversely isotropic rectangular elastic blocks [PDF]

open access: yes, 2007
In this paper we examine the classical problem of finite bending of a rectangular block of elastic material into a sector of a circular cylindrical tube in respect of compressible transversely isotropic elastic materials.

Elastic-Plastic Stress Behaviour of FGM Cylinders under Thermal and Rotational Loads: Role of Material Gradation, Temperature and Rotational Speed in Plastic Zone Propagation [PDF]

open access: yesChemical Process Design
The primary objective of this study is to analyze the impacts of thermal loading, material composition, radius ratios, and rotational speeds on the initiation and progression of plastic zones in functionally graded cylinders. To achieve this, the problem

Modelling and analysis of elastic and thermal deformations of a hybrid journal bearing

open access: yesTribology International, 2018
Abstract The continuous demand for higher power density leads to a very challenging operational environment for sliding bearings regarding pressures and deformations. Understanding of the deformation behavior of heavily loaded bearings becomes even more pronounced when modern hybrid multilayer designs are considered.
