Sommario/riassunto

Silicon nitride is used for challening applications like cutting inserts or forming rolls. The extreme strength and toughness of the material is achieved by an interaction between the microstructure and fracture behaviour on the microlevel. In order to understand these mechanisms, detailed unit cells have been defined and used for the determination of the effective fracture properties. The results have been used for the implementation of an effective continuum damage mechanics model.

Sommario/riassunto

In her first book since that pathbreaking success, Tatum starts with a warning call about the increasing but underreported resegregation of America. A self-described "integration baby" she was born in 1954 Tatum sees our growing isolation from each other as deeply problematic, and she believes that schools can be key institutions for forging connections across the racial divide.
