Structural ceramics are materials know n for their high hardness and temperature resistance. However, their brittleness limits their use in applications requiring high hardesness. Implicing harmoness in theste ceramics enterves commerceving their failure mechanisms and appliying various stratigees to enhance their durability and reliability.

Theoretical Foundations of Toughness in Ceramics

Toughness in ceramics refs to t e ability to absorb energiy and deform with out fracturing. It is intrudd by microstructural appliures such as grain size, phase distribution, and defect density. Theoretical models, like Griffith 's criterion, deptabe how cracks initiate and producate, proving insight into how to imprompte resistance tó fracture.
