摘要

Abstract

[Objective]To explore the effect of structural elasticity on the ice-structure interaction process,model tests on the interaction between frozen ice and elastic plates were conducted in a low-temperature labo-ratory.This study aims to provide a theoretical basis for understanding the ice-structure interaction mecha-nism and predicting ice loads on ships operating in ice-covered areas.[Method]In the experiments,the stiffness of the elastic plates was adjusted by varying their thickness.Two loading rates within the strain-rate range associated with brittle ice failure were selected.A universal testing machine was used to record load-time history data,and a CCD camera was employed to capture the ice failure modes under different test condi-tions.[Results]The interaction process consists of two typical phases:the loose contact phase and the tight contact phase.Loose contact results from the uneven contact between the plate and the top of the ice specimen,with maximum displacements generally ranging from 0 to 1.5 mm.In the tight contact phase,about 43.3%of the load-displacement curves show a saw-tooth shape,representing multi-stage failure modes.Stiffer plates are more likely to cause single-stage ice failure,while more flexible plates tend to result in multi-stage failures.Multi-stage failures are associated with ice flaking at a 45° angle due to shear failure.During multi-stage fail-ure,the slope of the load-displacement curve remains nearly constant,suggesting constant stiffness of the ice-elastic plate coupling system in the tight contact phase.[Conclusion]Although the structure in this study is simplified as a plate,the experimental results provide valuable insights for designers of ice-going ships into the complex interaction mechanics between ice and ship structures.This research also provides a foundation for further studies on more complex structures and accurate ice load predictions.
