This work presents a coupled fluid-structural interaction (FSI) capability wherein pressure and thermal loads predicted by the CRUNCH CFD and CRAFT CFD Navier-Stokes solvers are exchanged with Abaqus/Standard and Abaqus/Explicit using the Co-Simulation Engine (CSE). Multiple domains may be simulated concurrently, on separate groups of processors. Data exchange is handled through SIMULIA’s Co-Simulation Engine API. The boundary surface common to the fluid and solid domains is defined, along with the specific scalar and/or vector fields to be exchanged. Point forces or pressures, heat fluxes, displacements, and temperatures are passed between the codes, and simulations may be either one-way or two-way coupled. Applications of the FSI simulation capability to problems of interest are presented and discussed.

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.
