ABSTRACT Numerous engineering applications exist for the piezoelectric effect, which results from electromechanical coupling between electrical and mechanical fields. In-plane vibrations of plates’ resonance frequencies associated mode shapes have been thoroughly investigated. However, analytical solutions in-plane-dominated thick circular plates are limited. In this paper, higher-order plate t...
even though, to date, a lot of studies have been conducted on the subject of politeness theory, there are very few studies regarding the applicability of this theory to translation between english and persian which shows the reason behind conducting the present study. this study was carried out with the aim of highlighting whether there is any difference between english and persian methods of u...
Two effective quasi – static models are presented to consider pre and post- failure behaviors of the clamped circular plates subjected impulsive loads based on upper bound limit analyses of deformation. In first model, it is assumed that final profile is considered to have a conical shape, which is represented by radial and vertical motions of a single peripheral plastic hinge permanent deflect...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
Recent research showed that the in-plane horizontal displacement capacity of unreinforced masonry (URM) walls depends on numerous factors that are not yet captured by current empirical drift capacity models; e.g., axial stress, shear span, geometry of the walls and the material used. In order to improve the performance-based assessment of URM wall buildings, future research should aim at develo...
While elastoplasticity theories at small deformations are well established for various materials, elastoplasticity theories at large deformations are still a subject of controversy and lively discussions. Among the approaches to finite elastoplasticity two became especially popular. The first, implemented in the commercial finite element codes, is based on the introduction of a hypoelastic cons...
This paper is devoted to deformation theory of graded Lie algebras over Z or Zl with finite dimensional graded pieces. Such deformation problems naturally appear in number theory. In the first part of the paper, we use Schlessinger criteria for functors on Artinian local rings in order to obtain universal deformation rings for deformations of graded Lie algebras and their graded representations...
In the past decades, time ordered perturbation theory was very successful in describing relativistic scattering processes. It was developed for local quantum field theories. However , there are field theories which are governed by non-local interactions, for example non-commutative quantum field theory (NCQFT). Filk [1] first studied NCQFT perturbatively obtaining the usual Feynman propagator a...
