Download or read book New Contributions to R-curves and Bridging Stresses - Applications of Weight Functions written by Theo Fett and published by KIT Scientific Publishing. This book was released on 2014-07-31 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most ceramics show an increase of the crack growth resistance during crack propagation (R-curve behaviour). Reasons for such behaviour are bridging effects between opposite crack surfaces, phase transformations around the tip of a crack, and development of micro-cracking zones.This booklet predominantly deals with the bridging behaviour and the discussion of the observed effects in terms of the fracture mechanics weight function procedure.
