Development of constitutive equations for hot working of titanium matrix composites [PDF]

MATEC Web of Conferences, 2020
This research is devoted to modelling the viscoplastic deformation behaviour and microstructure evolution of particle reinforced titanium matrix composites (TMCs) at hot working conditions.

On the out-of-plane deviation of the bending deformation states of moderately thick bars of asymmetric cross-sections

Engineering Transactions
A characteristic feature of the six-parameter theories of bars is a coupled form of the constitutive equations; in particular the equations linking transverse forces with transverse shear deformations cannot be, in general, decoupled, keeping a ...

Generalized diffusion theory of micromorphicly deformable particle-fluid continuum and bubble-liquid two-phase flows

Vietnam Journal of Mechanics, 1993
In the paper [1] the basic concepts and equations were derived for the micromorphicly deformable particle-fluid two-phase flows, the constitutive equations have been constructed.

A Solution Set-Based Entropy Principle for Constitutive Modeling in Mechanics

, 2018
Entropy principles based on thermodynamic consistency requirements are widely used for constitutive modeling in continuum mechanics, providing physical constraints on a priori unknown constitutive functions. The well-known M\"uller-Liu procedure is based

Mixed FEM for Shells of Revolution Based on Flow Theory and its Modifications

Structural Mechanics of Engineering Constructions and Buildings
For describing elastoplastic deformation, three versions of constitutive equations are used. The first version employs the governing equations of the flow theory.

Transient thermal regime trough the constitutive matrix applied to asynchronous electrical machine using the cell method

Open Physics, 2018
In this paper, a new constitutive matrix for thermal conduction in transient thermal regime is developed and tested. We use cell method as a numerical method that is included in finite formulation methodology.

Coupled systems of fractional equations related to sound propagation: analysis and discussion [PDF]

, 2012
In this note we analyse the propagation of a small density perturbation in a one-dimensional compressible fluid by means of fractional calculus modelling, replacing thus the ordinary time derivative with the Caputo fractional derivative in the ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Constitutive memory equations for auxetic materials

Mathematical Modelling and Analysis
In this note we suggest a set of constitutive equations for anelastic materials whose internal structure can present anomalous variations resulting from external effects of tension/compression, as in auxetic media. For these problems we require of a new
