The failure diagrams show that the studied ice types demonstrate various
behavior during the test under consideration and variations in the beam length. It
can be seen that:
• Ice crushing under indenter forcing in the initial stage of the beam loading is
almost not distinguished from the force record in the sea ice; it can be identified
in the model columnar ice at some tests and it clearly appears in the model
fine-granule ice (FG type).
