In aircraft bleed air system ducts, cracks may exist or initiate from manufacturing defects in areas of high stress concentration in particular at welds. The initial minor cracks may grow into two possible failures: either the crack grows steadily through the wall to form a stable “through-crack” (leak-before-break), or it becomes unstable before or after it has reached the opposite surface of the duct wall and spreads rapidly over a large portion of the duct (break-before-leak), depending on the pressurized hot-air load and the toughness of material. For the safe design of bleed air system ducts and assessment of ducts with minor cracks found in the quality inspection, it is required to understand and predict the crack behavior and leak-before-break leakage rate.

The firing process of ceramic products under a specific heat curve is generally divided into three different phases: thermal expansion, sintering, and thermal contraction phases. These non-mechanical deformations are assumed to be unrelated, and the mechanical ones are assumed to be represented by the viscoplastic constitutive model. The key issue is how to determine sintering strains by calibrating the employed function forms of the densification rate with the data obtained from the stairway thermal cycle (STC) test. In addition, the presentations of the dependencies of the elastic and creep properties on both temperature and density are of importance to accurately predict the overall deformation of ceramic products.

Due to size effect in nanotechnology, an appropriate pressure-dependent model is required to define the material yielding in ceramics. Current pressure-dependent models, such as the Mohr-Coulomb and Drucker-Prager (DP) models, have specific shapes and thus cannot be flexibly applied to ceramic materials. This study develops a constitutive model, an integration algorithm, and consistent tangent operators for a piecewise Drucker-Prager (PDP) model. The constitutive model with considering strain hardening with yield flows is derived. The integration algorithm is developed based on return mapping (to smooth portion, apex and corner). The consistent tangent operators are established for each return mapping case.
