• A Review of Hyperelastic Constitutive Models for Dielectric Elastomers

  Publikacja

  • S. Dastjerdi
  • M. Malikan
  • V. Eremeev

  - Rok 2023

  Dielectric elastomers are smart materials that are essential components in soft systems and structures. The core element of a dielectric elastomer is soft matter, which is mainly rubber-like and elastomeric. These soft materials show a nonlinear behaviour and have a nonlinear strain-stress curve. The best candidates for modelling the nonlinear behaviour of such materials are hyperelastic strain energy functions. Hyperelastic functions...

• A hyperelastic model for soils with stress-induced and inherent anisotropy

  Publikacja

  • M. Cudny
  • K. Staszewska

  - Acta Geotechnica - Rok 2021

  In this paper, modelling of the superposition of stress-induced and inherent anisotropy of soil small strain stiffness is8presented in the framework of hyperelasticity. A simple hyperelastic model, capable of reproducing variable stress-induced9anisotropy of stiffness, is extended by replacement of the stress invariant with mixed stress–microstructure invariant to10introduce constant inherent cross-anisotropic component. A convenient...

• Modelling tunnelling-induced deformation in stiff soils with a hyperelastic–plastic anisotropic model

  Publikacja

  • M. Cudny
  • K. Lisewska
  • M. Winkler
  • T. Marcher

  - Acta Geotechnica - Rok 2024

  In this paper, the tunnelling-induced deformation in anisotropic stiff soils is analysed using FE modelling. The influence of material description is investigated rather than an advanced simulation of the tunnelling method. A new hyperelastic– plastic model is proposed to describe the anisotropic mechanical behaviour of stiff highly overconsolidated soil. This model can reproduce the superposition of variable stress-induced anisotropy...

  - MACROMOLECULAR MATERIALS AND ENGINEERING - Rok 2017

  The poor knowledge about nonlinear mechanical behavior of elastomer nanocomposites arises from the incomplete information on the interface. Application of hyperelastic models provides more insights into the nature and the situation of interaction between the elastomeric matrix and nanofillers. The current work seeks to address the effect of interphase strength on tensile properties of the elastomer nanocomposites under large deformations....

• Hyperelastic Microcantilever AFM: Efficient Detection Mechanism Based on Principal Parametric Resonance

  Publikacja

  • S. Rahmanian
  • S. Dastjerdi
  • M. Malikan
  • K. Behrouz
  • B. Akgöz
  • Ö. Civalek

  - Nanomaterials - Rok 2022

  The impetus of writing this paper is to propose an efficient detection mechanism to scan the surface profile of a micro-sample using cantilever-based atomic force microscopy (AFM), operating in non-contact mode. In order to implement this scheme, the principal parametric resonance characteristics of the resonator are employed, benefiting from the bifurcation-based sensing mechanism. It is assumed that the microcantilever is made...

• Nonlinear Free and Forced Vibrations of a Hyperelastic Micro/Nanobeam Considering Strain Stiffening Effect

  Publikacja

  • A. Alibakhshi
  • S. Dastjerdi
  • M. Malikan
  • V. Eremeev

  - Nanomaterials - Rok 2021

  In recent years, the static and dynamic response of micro/nanobeams made of hyperelasticity materials received great attention. In the majority of studies in this area, the strain-stiffing effect that plays a major role in many hyperelastic materials has not been investigated deeply. Moreover, the influence of the size effect and large rotation for such a beam that is important for the large deformation was not addressed. This...

• Uniform Model Interface for Assurance Case Integration with System Models

  Publikacja

  • A. Wardziński
  • P. Jones

  - Rok 2017

  Assurance cases are developed and maintained in parallel with corresponding system models and therefore need to reference each other. Managing the correctness and consistency of interrelated safety argument and system models is essential for system dependability and is a nontrivial task. The model interface presented in this paper enables a uniform process of establishing and managing assurance case references to various types...

• Young’s modulus distribution in the FEM models of bone tissue

  Publikacja

  • K. Mazur
  • L. Dąbrowski

  - Rok 2013

  This paper presents how differences of Young’s modulus in adjacent finite elements typical for organic materials such as bone tissue, influence stress calculating. Emphasizing high computational cost of variable Young’s modulus in parts of the model, where the number of finite elements has been raised, the authors wants to prove that new model of finite element which has variable Young’s modulus in its volume needs to be created....
