GLOBAL ATTRACTOR FOR THE NONLINEAR STRAIN WAVES IN ELASTIC WAVEGUIDES
Nonlinear strain waves attrac
2007/12/10
In this paper the authors consider the initial boundary value problems of the generalized nonlinear strain waves in elastic waveguides and prove the existence of global attractors and the finiteness o...
Relaxation oscillations and negative strain rate sensitivity in the Portevin - Le Chatelier effect
Relaxation oscillations strain rate Portevin - Le Chatelier effect
2010/11/2
A characteristic feature of the Portevin - Le Chatelier effect or the jerky flow is the stick-slip nature of stress-strain curves which is believed to result from the negative strain rate dependence ...
