TL;DR: In this article, Nayfeh and Mook considered the nonlinear dynamic response of a relief valve and showed the discreapancies between the two methods for this specific problem.

TL;DR: In this article, the influence of the magnetic field on the flow properties in situations where the particle phase is considered dense enough to include the particulate viscous stresses was investigated. But the authors focused on the effect of the presence of solid particles on the performance of such devices.

TL;DR: In this article, a finite element formulation of the bound theorems for anisotropic soils is presented, which allows for the variation of soil strength with direction, and the conventional isotropic Mohr-Coulomb yield criterion is generalized to include the effect of strength anisotropy.

TL;DR: In this article, an integral differential equation (IDE) in the time domain is proposed for the free vibration of a single-degree-of-freedom (SDOF) system with hysteretic damping which is different from the conventional complex stiffness model as employed in the frequency domain.

TL;DR: In this paper, the dependence of chaotic motions on the beam model was discussed. But the authors focused on the appearance of chaotic motion in the more refined beam models, rather than the Bernoulli-ruler model.

TL;DR: In this article, the authors used the concept of dissipative force k to describe the thermodynamic stimulus of a phase transition in a pseudoelastic straining of CuZnAl monocrystals.

TL;DR: In this paper, the authors considered the problem of determining necessary and sufficient conditions for the existence of symmetry planes of an anisotropic elastic material and used these conditions to determine special coordinate systems where the number of non-zero components in the elasticity tensor is minimized.

TL;DR: In this paper, the authors present a numerical study for the bifurcations of a softening Duffing oscillator subjected to stationary and non-stationary excitation.

TL;DR: In this paper, simple shear tests of sand along steel plates have been simulated numerically using a finite element method and an elasto-plastic Cosserat model.

TL;DR: In this paper, the free convection flow over a vertical cone immersed in a stratified medium has not been studied so far, which has motivated us to carry out the present analysis.

TL;DR: In this article, a two-phase fluid-particle flow model is developed and applied to the problem of steady, laminar flow over an infinite porous flat plate, where both phases are assumed to behave as non-Newtonian power-law fluids.

TL;DR: In this paper, a nonlinear finite element method for the transient dynamic analysis of a rotating flexible beam carrying a static payload is presented, which makes use of the Lagrange formulation in homogeneous coordinates.
