Nine fracture and four tensile tests were conducted on 5m x 5m and 10m x 10m edge-notched sea ice plates during Austral spring 2001. The dataset contains physical property profiles, cyclic loading responses, and acoustic emission data from in-situ experiments in McMurdo Sound. The study was conducted by the organization SCIOPS to develop models of sea ice breakup.
Use Cases
- Modeling fracture toughness by analyzing crack opening displacement (CMOD, COD, NCTOD) measurements under cyclic loading.
- Correlating ice microstructure from thin-section micrographs with its salinity, density, and temperature profiles.
- Predicting micro-cracking activity using acoustic emission (AE) transducer data from the crack tip process zone.
- Calibrating constitutive models of sea ice using load-to-failure data from tensile and fracture tests on 1.4m thick ice.
Strengths
- In-situ data from 13 distinct mechanical tests (9 fracture, 4 tensile) on full-thickness sea ice.
- Multifaceted measurements include physical property profiles, microstructure imaging, mechanical loading, and acoustic emissions.
Limitations
- Limited sample size of 13 tests conducted at a single location (McMurdo Sound) during one season.
- Unknown total row count and data granularity for the recorded profiles and time-series measurements.
