Abstract
A new method for the visualization of plastic flow localization is proposed which is based on first-order statistics of laser speckle patterns. The specific features, applicability and limitations of the proposed method are considered. The setup designed for sample testing is described. The equipment developed has space and time resolution of ∼0.03 mm and ∼1 s -1, respectively, and makes feasible the real-time investigation of plastic deformation processes. The experimental evidence obtained for plastic flow localization in commercial aluminum alloy is considered.
