A technique for determining Young's modulus of biological

A technique for determining Young's modulus of biological

Oct 01, 2016 Young's modulus of polylysine increases abruptly (by 7 times) below 90 K compared with the values obtained for room temperatures. The observed difference, namely, a sharp rise on the temperature curve of the elastic properties of polylysine at about 80 K, is likely caused by the structural modification of the polymer under these conditions.

Stochastic model of the stroke of a two mass cone crusher

Stochastic model of the stroke of a two mass cone crusher

Jun 29, 2020 The mode of a two-mass cone crusher at the approaches to one of the Sommerfeld thresholds is considered. Frequency close to this threshold from low side provides the most efficient energy transfer from the unbalance to the crusher body. However, the stochastic model of crushing shows the possibility of breakdown such mode even after a very long stay on it.

Polymer Fibers in Foam Concrete Application Efficiency

Polymer Fibers in Foam Concrete Application Efficiency

Feb 23, 2003 The urgency of improving the performance properties of concrete, as the most common building materials, is noted. The reasons for the increased demand for products made of high-strength gas-filled concrete are stated. It is shown that the current volume of polymer fibers production makes it possible to predict the possibility of their widespread use in construction.

Dec 01, 2019 In this case, the elasticity modulus reflects the structure of the austenite and is estimated for different alloys in the range of 40–75 GPa; breaking strength is estimated at σ в ≈ 800–1150 MPa, tensile strength is estimated at ε ≈ 0.4–0.5 and the Poisson ratio is estimated at ν ≈ 0.33. These data were used in the simulation.

Stability Loss in an Infinite Plate with a Circular

Loss of stability under uniaxial tension in an infinite plate with a circular inclusion made of another material is analyzed. The influence exerted by the elastic modulus of the inclusion on the critical load is examined. The minimum eigenvalue corresponding to the first critical load is found by applying the variational principle.

Abstract In this paper, the stability of axisymmetric equilibrium modes of inhomogeneous circular plates with an elastically restrained edge, which are subjected to a normal pressure, is discussed. Assuming that the asymmetric component of the solution is periodic, the numerical method is used to determine the lowest load value, at which a bifurcation into the asymmetric state occurs. The ...
