Crack bifurcation in laminar composite ceramics with rigid interlaminar connection

摘要

Crack bifurcation in a symmetric two-component laminar composite has been studied. Geometries restricting this effect realization have been established. Bifurcation area is determined by the following parameters: the number of layers, cooling temperature range, elastic constants, and the layer thermal expansion coefficients. Bifurcation constraints in the specimen with a given composition layer number are correlated to those for the specimen with a fixed stacked thickness.
