Microcrack interaction with a main crack bridged by ductile particles Part I: Colinear Microcrack
. Moreover, asingle collinear microcrack on a continuation of the main crack is considered. Such a configuration of the microcrack shows a deleterious effect on fracture between a main, bridged crack and neighbouring microcrack<...

Nonlinear Behavior in Compression and Tension of Thermally Sprayed Ceramic Coatings
nonlinear. Under compressive stresses, elastic closing of microcracks leads to a gradual decrease of the microcrack density and to an increase of Young?s modulus in compression. Under tensile stresses, the microcracks slig...
