• Surface finite viscoelasticity and surface anti-plane waves

  Publikacja

  • V. Eremeev

  - INTERNATIONAL JOURNAL OF ENGINEERING SCIENCE - Rok 2024

  We introduce the surface viscoelasticity under finite deformations. The theory is straightforward generalization of the Gurtin–Murdoch model to materials with fading memory. Surface viscoelasticity may reflect some surface related creep/stress relaxation phenomena observed at small scales. Discussed model could also describe thin inelastic coatings or thin interfacial layers. The constitutive equations for surface stresses are...

• On the Bending of Multilayered Plates Considering Surface Viscoelasticity

  Publikacja

  • V. Eremeev
  • V. Konopińska-Zmysłowska

  - Rok 2022

  We discuss the bending resistance of multilayered plates taking into account surface/interfacial viscoelasticity. Within the linear surface viscoelasticity we introduce the surface/interfacial stresses linearly dependent on the history of surface strains. In order to underline the surface viscoelasticity contribution to the bending response we restrict ourselves to the elastic behaviour in the bulk. Using the correspondence principle...

• An isogeometric finite element formulation for boundary and shell viscoelasticity based on a multiplicative surface deformation split

  Publikacja

  • K. Paul
  • R. Sauer

  - INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING - Rok 2022

  This work presents a numerical formulation to model isotropic viscoelastic material behavior for membranes and thin shells. The surface and the shell theory are formulated within a curvilinear coordinate system,which allows the representation of general surfaces and deformations. The kinematics follow from Kirchhoff–Love theory and the discretization makes use of isogeometric shape functions. A multiplicative split of the surface...

• Alternative Approach to Convolution Term of Viscoelasticity in Equations of Unsteady Pipe Flow

  Publikacja

  • K. Weinerowska-Bords

  - JOURNAL OF FLUIDS ENGINEERING-TRANSACTIONS OF THE ASME - Rok 2015

  In the paper the selected aspects concerning description of viscoelastic behavior of pipe walls during unsteady flow are analyzed. The alternative convolution expression of the viscoelastic term is presented and compared with the corresponding term referring to unsteady friction. Both approaches indicate similarities in the forms of impulse response functions and the parameter properties. The flow memory was introduced into convolution...

• Nonlinear viscoelasticity in Three Dimensional filler reinforced rubber composites and nanocomposites

  Publikacja

  • M. Strankowski

  - Advances in Polymer Science - Rok 2014

  This chapter describes the influence of three-dimensional nanofillers used in elastomers on the nonlinear viscoelastic properties. In particular, this part focuses and investigates the most important three-dimensional nanoparticles, which are used to produce rubber nanocomposites. The rheological and the dynamic mechanical properties of elastomeric polymers, reinforced with spherical nanoparticles, like POSS, titanium dioxide and...

• The dependence of linear viscoelasticity limits of cold-recycled mixtures on time of curing and compaction method

  Publikacja

  • M. Jaczewski
  • C. Szydłowski
  • B. Dołżycki

  - Materials Today: Proceedings - Rok 2023

  Cold-recycled mixtures are currently among the most widely used and investigated methods that enable recycling of old pavement structures in an environmentally friendly manner. Upon milling, the old pavement structure – whose gradation can be improved with addition of virgin aggregate – is mixed and compacted at ambient temperature. The main binding agents are bituminous emulsion and cement. Due to their dual binding behaviour,...
