Fracture and Size Effect in Concrete and Other Quasibrittle Materials (eBook, ePUB)

• Format: ePub

Produktbeschreibung

The book is the first in-depth text on the application of fracture mechanics to the analysis of failure in concrete structures. It synthesizes a vast number of recent research results in the literature to provide a comprehensive treatment of the topic that does not give merely the facts - it provides true understanding.
