Dynamic yield stresses of glasses: asymptotic formulae
نویسندگان
چکیده
The stationary, shear rate dependent flow curves of yielding glasses are discussed within a mode coupling theory approach. Asymptotic formulae for the shear stress at the transition point are obtained that take the form of generalized Hershel–Bulkeley constitutive equations, and enable one to find dynamical yield stresses by extrapolation. (Some figures in this article are in colour only in the electronic version)

Initiation of shear bands near a stress concentration in metallic glass
Instrumented contact experiments are performed on three metallic glasses to systematically study shear band formation near a stress concentration. The results suggest that high local stresses at a point in the glass are insufficient to initiate a shear band. Rather, the yield strength must be exceeded along the entire length of a viable shear path in order for a shear band to form. Because of t...
متن کاملPermanence and Uniformly Asymptotic Stability of Almost Periodic Positive Solutions for a Dynamic Commensalism Model on Time Scales
In this paper, we study dynamic commensalism model with nonmonotic functional response, density dependent birth rates on time scales and derive sufficient conditions for the permanence. We also establish the existence and uniform asymptotic stability of unique almost periodic positive solution of the model by using Lyapunov functional method.
متن کاملReentrancy and Dynamic Specific Heat of Ising Spin Glasses
The dynamic susceptibility and dynamic specific heat of Ising spin glasses with non-symmetric distributions of the exchange couplings are studied by the Monte Carlo method and are compared to the results obtained previously by the local mean field method. The two methods yield qualitatively different results but they still suggest lack of
متن کاملApproximate Closed-form Formulae for Buckling Analysis of Rectangular Tubes under Torsion
The buckling torque may be much less than the yield torque in very thin rectangular tubes under torsion. In this paper, simple closed-form formulae are presented for buckling analysis of long hollow rectangular tubes under torsion. By the presented formulae, one can obtain the critical torque or the critical angle of twist of the tube in terms of its geometrical parameters and material constant...

Abstract In this paper, the effect of strain rate sensitivity of materials in the case of a fully clamped circular plate has been discussed introducing a new criterion called "dynamic to static collapse pressure ratio". In order to do so, a simple mass and wire model is assumed. Then, using Cowper-Symonds constitutive relation and Perrone-Bhadra Simplifications, the mean strain rate of su...
