Investigation of the Acoustic Emission and Deformation Response of Finite Ice Plates

A procedure is described for monitoring the microfracturing activity in ice plates subjected to constant loads. Sample time records of freshwater ice plate deflections as well as corresponding total acoustic emission activities are presented. The linear elastic, as well as viscoelastic, response for...

Description
Summary:A procedure is described for monitoring the microfracturing activity in ice plates subjected to constant loads. Sample time records of freshwater ice plate deflections as well as corresponding total acoustic emission activities are presented. The linear elastic, as well as viscoelastic, response for a simply supported rectangular ice plate is given. Suggested future work using the above procedure is discussed. (Author)
