Microstructurally Short Cracks in Polycrystals Described by Crystal Plasticity [PDF ebook] 

Microstructurally short cracks with lengths up to about ten grains are known to be strongly influenced by the microstructural features in the neighborhood of the crack tip. These include randomly shaped and oriented crystal grains and strongly orientation dependent deformation behavior of the grains. This new book proposes computational models aiming to quantify the effects of random grain orientations on the variability of crack tip opening and sliding displacements (CTOD, CTSD).
