plastic deformation during the fracture. A ductile fracture is characterized by considerable amount of plastic deformation prior to and during the crack propagation. On the other hand, brittle fracture is characterized by micro-deformation or no gross deformation during the crack propagation. Plastic deformation that occurs during ductile

Based on the findings of the deformation experiments and microstructural observations, we discuss the effects of microparticles and GBs on the deformation of ice-sheet ice, and we propose a possible reason for the observed rapid deformation of ice-age ice. 2.

plastic deformation and crack propagation. Furthermore FEM elasto- plastic analysis coupled with transient heat condition analysis was performed. The analytical results were good agree with the experimental ones and the propriety of this non-contact measurement system of plastic deformation and fracture process by theromgraphy system was shown. .
