in this paper, the interface crack of two non-homogenous functionally graded materials is studied. subsequently, with employing the displacement method for fracture of mixed-mode stress intensity factors, the continuous variation of material properties are calculated. in this investigation, the displacements are derived with employing of the functional graded material programming and analysis o...

Abstract The prestressed anchor cable can improve the overall stability of rock and soil mass slope, thereby improving mechanical properties mass, better control structural displacement, achieve purpose reducing landslides, dangerous rocks rocks. At same time, pre-stressed construction is convenient, fast in progress, economical, has a broad application space. Based on actual engineering backgr...

Tuned mass damper inerter (TMDI) is commonly reported to be a lightweight tunable device that can significantly reduce buildings' seismic response. However, the backward action produced by and returned building in conventional TMDIs may either performance or limit potential. This study proposes investigates novel control scheme using large physical ratios generated inerters. Hence, double tuned...

an analytical solution is presented for displacements and stresses of a three dimensional linear hyperelastic transversely isotropic layer bonded on the top of a transversely isotropic half-space subjected to an arbitrary, time-harmonic surface tangential force. the equations of equilibrium in terms of displacements are uncoupled by using a set of two potential functions introduced by eskandari...

background: centre of pressure displacement is an indicator of postural control. children with cerebral palsy have poor postural control. one common intervention to enhance their balance is vestibular stimulation. the aim of this research was to investigate the effect of vestibular stimulation on cop parameters in children with cerebral palsy (3-10 years old). methods: this study was a randomiz...

We analyze the incompressible flow past a square cylinder immersed in wake of an upstream splitter plate, which separates two streams different velocities, U T (top) and B (bottom). The Reynolds number associated with below plate is kept constant at [Formula: see text], based on side D as characteristic length. top-to-bottom dissymmetry measured by ratio text] between numbers above plate. equiv...

Underground displacement monitoring is an effective method to explore deep into rock and soil masses for execution of subsurface displacement measurements. It is not only an important means of geological hazards prediction and forecasting, but also a forefront, hot and sophisticated subject in current geological disaster monitoring. In previous research, the authors had designed a novel electro...

o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...
