摘要: We study the intermittency and noise of dislocation systems undergoing shear deformation. Simulations a simple two-dimensional discrete dynamics model indicate that deformation rate exhibits power spectrum scaling type 1/falpha. The exponent is far away from Lorentzian, with alpha approximately 1.5. This result directly related to way durations avalanches plastic activity scale their size.
