Flexural strength and modulus of autopolimerized poly (methyl methacrylate) with nanosilica [PDF]

open access: yesVojnosanitetski Pregled, 2018
Background/Aim. Autopolymerized, or cold polymerized poly(methyl methacrylate) class of materials have a lower mechanical properties compared to hot polymerized poly(methyl methacrylate), due to a limited time of mixing before the polymerization process ...

Four simplified gradient elasticity models for the simulation of dispersive wave propagation [PDF]

open access: yes, 2008
Gradient elasticity theories can be used to simulate dispersive wave propagation as it occurs in heterogeneous materials. Compared to the second-order partial differential equations of classical elasticity, in its most general format gradient elasticity ...

Numerical study of the Sturm–Liouville problem [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
The article discusses the general Sturm–Liouville problem. To solve it numerically, a new algorithm is proposed, which is based on the varia-tional principle and does not use saturation.

Rubber elasticity [PDF]

open access: yesJournal of Chemical Education, 1981
Abstract Rubber elasticity may be operationally defined as very large deformability with essentially complete recoverability. In order for a material to exhibit this type of elasticity, three molecular conditions must be met: (1) the material must consist of polymeric chains, (2) the chains must be joined into a network structure, and (3) the ...

A higher order control volume based finite element method to prodict the deformation of heterogeneous materials [PDF]

open access: yes, 2013
Materials with obvious internal structure can exhibit behaviour, under loading, that cannot be described by classical elasticity. It is therefore important to develop computational tools incorporating appropriate constitutive theories that can capture ...

A theoretical analysis of price elasticity of energy demand in multi-stage energy conversion systems [PDF]

open access: yes, 2003
The objective of this paper is an analytical exploration of the problem of price elasticity of energy demand in multi-stage energy conversion systems. The paper describes in some detail an analytical model of energy demand in such systems.

Nanoparticle elasticity regulates phagocytosis and cancer cell uptake

open access: yesScience Advances, 2020
The deformation of soft nanocapsules during cell binding and endocytosis leads to a lower cellular uptake than the stiff ones. The ability of cells to sense external mechanical cues is essential for their adaptation to the surrounding microenvironment ...

Learning hidden elasticity with deep neural networks [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Elastography has been applied to medical imaging to detect cancerous tissues for decades. The conventional elastography based on the assumption of stress uniformity is prone to inaccuracies. Accurately reconstructing elasticity distributions
