A circular elastic disk is coated with an beam, absorbing shear and normal forces without deformation linearly reacting to a bending moment change in curvature. The inextensibility of the beam introduces isoperimetric constraint, so that length initial circumference constrained remain fixed during loading disk/coating system. mechanical model for this system formulated, solved general loading, ...

for finding the optimal choices of applied remote loads – normal force, moment, shear force and bulk stresses needed to solve frictional contact problems in partial-slip using half-plane theory are derived by data from contacts analysed finite element method. While forces moment readily found equilibrium considerations, order determine we must exploit details traction ratio direct strain within...

due to the existence of fibrous materials such as plastic fragments, the strength anisotropy of municipal solid waste (msw) materials is the main source of differences between their mechanical response in direct shear and triaxial apparatus. as an extension of earlier research on the mechanical behavior of msw using a large traixail apparatus, results presented in shariatmadari et al. [1] and k...

where ν is the unit normal to ∂Ω and the superscript t indicates transposition (in this case, of the matrix ∇~u = (∂ju)j,α). Relying on the method of layer potentials and suitable Rellich-NečasPayne-Weinberger formulas, the boundary value problems (1.2)-(1.3) with ~ f = 0 and ~g ∈ L(∂Ω), 2− ε < p < 2 + ε, have been treated (in all spacedimensions) by B. Dahlberg, C.Kenig, and G.Verchota (cf. [7...

A Trigonometric Shear Deformation Theory (TSDT) for the analysis of isotropic plate, taking into account transverse shear deformation effect as well as transverse normal strain effect, is presented. The theory presented herein is built upon the classical plate theory. In this displacement-based, trigonometric shear deformation theory, the in-plane displacement field uses sinusoidal function in ...

Relations between primary oesophageal peristaltic amplitude and traction force were studied in 30 normal volunteers, 12 patients with functional dysphagia, and 48 patients with gastro-oesophageal reflux disease, using a new intraluminal strain gauge device. Forces generated by swallowing in the normal oesophagus were 42 (35-60) g (median and interquartile range), a close positive correlation ex...

This article presents Navier type closed-form solutions for static bending, elastic buckling and free vibration analysis of symmetric functionally graded (FG) sandwich beams using a hyperbolic shear deformation theory. The beam has FG skins and isotropic core. Material properties of FG skins are varied through the thickness according to the power law distribution. The present theory accounts fo...

In this article, a new higher order shear deformation theory based on trigonometric shear deformation theory is developed. In order to consider the size effects, the nonlocal elasticity theory is used. An analytical method is adopted to solve the governing equations for static analysis of simply supported nanoplates. In the present theory, the transverse shear stresses satisfy the traction free...
