Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...

We explore the use of Large Amplitude Oscillatory Shear (LAOS) deformation to probe the dynamics of shear-banding in soft entangled materials, primarily wormlike micellar solutions which are prone to breakage and disentanglement under strong deformations. The state of stress in these complex fluids is described by a class of viscoelastic constitutive models which capture the key linear and nonl...

The combined effects of nanoparticle and magnetic field on the nonlinear Jeffery-Hamel flow are analyzed in the present study. The basic governing equations are solved analytically to nonlinear ordinary differential equation using perturbation method together with a semi-numerical analytical technique called Hermite- Padé approximation. The obtained results are well agreed with that of the Adom...

There are many interesting and challenging problems in the area of classical eld theories. This area has attracted the attention of algebraists, geometers, and topol-ogists in the past and has begun to attract more analysts. Analytically, the area ooers all types of diierential equation problems which come from the two basic sets of equations in physics describing fundamental interactions, name...

Light scattering at plasmonic nanoparticles and their assemblies has led to a wealth of applications in metamaterials and nano-optics. Although shaping of fields around nanostructures is widely studied, the influence of the field inside the nanostructures is often overlooked. The linear field distribution inside the structure taken to the third power causes third-harmonic generation, a nonlinea...

We present our results on the visualization of non-linear vector field topology. The underlying mathematics is done in Clifford algebra, a system describing geometry by extending the usual vector space by a multiplication of vectors. We started with the observation that all known algorithms for vector field topology are based on piecewise linear or bilinear approximation and that these methods ...

Bovine brucellosis is a zoonotic disease distributed worldwide and characterized by abortion and reducedfertility in cows. Since brucellosis eradication programme in Iran uses vaccination, test, slaughter andquarantine as control measures, it is essential to distinguish vaccine strains from strains that cause infectionsamong vaccinated cattle herds. We developed and evaluated a multiplex polyme...

Abstract The anomalous Hall effect in time-reversal symmetry broken systems is underpinned by the concept of Berry curvature band theory. However, recent experiments reveal that nonlinear (NHE) can be observed non-magnetic without applying an external magnetic field. emergence NHE under symmetric conditions explained terms non-vanishing dipole (BCD) arising from inversion breaking. In this work...

Nonlinear wrinkling of a compressed film on a soft substrate in the presence of inhomogeneous swelling actuation strain caused by solvent diffusion is studied. The simulation relies on a continuum model which integrates phase field microelasticity and Föppl-von Kármán plate theory. We show that the wrinkling morphologies developed in the diffusive domain exceeding a critical compression are con...
