In our research, the magnetic field-induced deformation of isotropic magnetorheological elastomer (MRE) discs loaded with two types magnetite and an iron powder were examined. A measurement system using a microscope camera was assembled, magnitude determined from optical contour obtained digital image processing. We found that MRE height-to-width aspect ratio 1:2 underwent expansion in directio...

Methods: Suppose Ø:S1->S2 is a map from the surface S1 to the surface S2, we define the derivative map of Ø is the linear map between the tangent spaces, dØ:TM(p)->TM(Ø(p)), induced by the map. Let J be the derivative map and define the deformation tensor as S=(JTJ)1/2. Instead of analyzing shape change based on the eigenvalues of the deformation tensor, we consider a new family of metrics, the...

This paper deals with the calculation of the elastic properties for single-walled carbon nanotubes (SWCNTs) under axial deformation and hydrostatic pressure using the atomistic-based continuum approach and the deformation mapping technique. A hyperelastic model based on the higher-order Cauchy-Born (HCB) rule being applicable at finite strains and accounting for the chirality and material nonli...

Photonic defect modes induced by in situ formation of an ill-defined defect layer is demonstrated in a cholesteric liquid crystal (CLC). The local deformation of the one-dimensionally periodic helical structure is achieved by means of the thermodielectric effect, which alters the pitch in the middle of the cholesteric structure. The defect-mode peak in the photonic band gap appears in the trans...

The objective of present study is to develop a finite element method (FEM) software system toward a large-scale computation of following seismic processes: (1) Accumulation of the stress around active faults in the crust, which is induced by a subduction of plates in a long time span (static deformation process); (2) Onset of an earthquake due to a dynamic sliding on the faults, which is induce...
