A locking-free anisotropic nonconforming rectangular finite element approximation for the planar elasticity problem
      
This paper deals with a new nonconforming anisotropic rectangular finite element approximation for the planar elasticity problem with pure displacement boundary condition.
      
Measurement of the dynamic modulus of elasticity of wood panels
      
This study investigated the dynamic modulus of elasticity (DMOE) of wood panels of Fraxinus mandshurica, Pinus koraiensis, and Juglans mandshurica using the natural frequency measurement system of fast Fourier transform (FFT).
      
The results were compared with the static modulus of elasticity (ES) tested by a mechanical test machine.
      
The main results are as follows: the modulus of elasticity of longitudinal resonance, measured by wavelet analysis, can replace the conventional static modulus of elasticity.
      
The modulus of rupture and modulus of elasticity did not clearly improve with the four different treatments.
      
The impacts of fractal dimensions on the soil properties were analyzed with the elasticity analysis and marginal yield analysis.
      
Based on the elasticity analysis and marginal yield analysis, the effect of PSD was more than those of ASD and SPD.
      
The longitudinal tensile modules of elasticity (MOE) ranged from 8.49 to 32.49 GPa.
      
The elasticity and hardness of the nanocomposite increased, and the indentation depth reduced with the increase of Fe3O4 content in the composites.
      
The elasticity of the solid rock has little influence on the seismic response of the deep soil layer.
      
Consideration was given to the discrete nature of variations of the mechanical structure and substantial structural elasticity induced by the flexible joint couplings of the framework elements.
      
In this case, however, the stable contact with the neck at θ → 0 when the modulus of elasticity E→ ∞, i.e., at the interaction between the hard sphere and hard plane, is also degenerated into the point contact.
      
Therefore, the main parameter of the medium determining the static magnetic susceptibility value is the ratio of the modulus of elasticity of matrix to the temperature.
      
Surface Dynamic Elasticity of Poly(ethylene oxide) Monolayers on a Water Surface
      
The methods of transverse and longitudinal surface waves and of oscillating barrier were used to measure a surface dynamic elasticity of poly(ethylene oxide) films spread on aqueous substrate within the frequency range of 0.001-520 Hz.
      
A comparison of static and dynamic values of the surface elasticity shows that the surface film at surface polymer concentrations higher than 0.4 mg/m2 cannot be considered already as purely two-dimensional film.
      
Temperature dependences of elasticity constants and viscosity coefficients for nematic phases of a tetrapalladium organyl-pentadecane system were experimentally studied.
      
For the high-temperature phase N2, the ratio of elasticity constants K3/K1≈ 3, whereas K3/K1≈ 10 for the low-temperature phase.
