Homogenization of linearized elasticity systems with traction condition in perforated domains

Electronic Journal of Differential Equations, 1999
In this paper, we study the asymptotic behavior of the linearized elasticity system with nonhomogeneous traction condition in perforated domains. To do that, we use the $H_e^0$-convergence introduced by M.

Evaluation of technical efficiency traditional agriculture among smallholder maize farmers in East Java [PDF]

E3S Web of Conferences
The low productivity of maize in traditional agriculture has worsened the demand and supply of maize production. This gap indicates the important role of the small farmer sector in producing maize.

Once Again on Preliminary Reference Earth Model

Earth and Space Science, 2020
We studied the isotropic ball using data of Preliminary Reference Earth Model (PREM). It is shown that such a ball should be either destructed or gone into a more stable equilibrium state with uneven distributed deformation under thermobaric condition of

Modeling Bloch Waves in Prestressed Phononic Crystal Plates

Frontiers in Materials, 2019
The study aims at investigating the effect of a generic state of prestress on the passbands and bandgaps of a phononic crystal plate. To this end, an Updated Lagrangian scheme is developed, consisting in a two-step procedure: first, a static ...

Synchronization of flexible sheets

, 2011
When swimming in close proximity, some microorganisms such as spermatozoa synchronize their flagella. Previous work on swimming sheets showed that such synchronization requires a geometrical asymmetry in the flagellar waveforms.

Inhomogeneous deformations and motions of elastic materials

Le Matematiche, 1991
Unsteady motions are discussed within the context of the linearized theory of elasticity, the neo-Hookean theory of elasticity and the theory of interacting continua.
