A manufacturing-driven ICME framework is proposed to model short fiber reinforced ceramic matrix composite via direct ink writing. Currently, there lacks efforts to investigate the effects of properties of short fiber reinforced ceramic matrix composites due to fiber alignment variance. A multi-scale modeling approach is presented to use representative volume elements to capture the homogenized mechanical behavior at various fiber aspect ratio and volume ratio. The orthotropic material properties are mapped to model the printing process. A series of tensile tests simulations show that with 20$^\circ$ standard deviation in fiber alignment, the fracture plane has the maximum local tensile stress range at 30 degree printing angle. This local tensile stress variation is shown the minimum at 90 degree When the standard deviation increases from 20 degree to 40 degree, the average tensile strength across the fracture plane decreases by 2%, but the stress variations increase 27.6%.

[52][53][54] To the author's knowledge, there does not currently exist a unified computational framework that directly connects the process parameters of CVI to the flexure response of 𝛼-SiC. The purpose of this study is to relate the structure of a CVI-treated porous 𝛼-SiC ceramic to its flexural strength directly as a function of the process parameters of pressure, temperature, reaction kinetics, and gas diffusivity.…”

The flexural strength variability of α‐ based ceramics at elevated temperatures creates the need for an Integrated Computational Materials Engineering (ICME) framework that relates the strength of a specimen directly to its manufacturing process. To create this ICME framework, a model must first be developed which establishes a relationship between the chemical vapor infiltration (CVI) process and parameters, the resulting mesoscale pores, and the overall macroscale flexural strength. Here, a nonlinear single‐pore model of CVI is developed used in conjunction with a four‐way coupled thermo‐mechanical damage model. The individual components of the model are tested and a sample system under a four‐point bending test is explored. Results indicate that specimens with an initial porosity greater than 30% require temperatures below 1273 K to maintain structural integrity, while those with initial porosities less than 30% are temperature‐independent, allowing for optimization of the CVI processing time without compromising strength.

A three-way coupled thermo-mechanical fracture model is presented to predict the damage of brittle ceramics, in particular 𝛼-SiC, over a wide range of temperatures (20-1400 • C). Predicting damage over such a range of temperatures is crucial for thermal protection systems for many systems such as spacecraft. The model, which has been implemented in MOOSE, is divided into three modules: elasticity, damage phase field, and heat conduction. Analytical approaches for determining crack lengthscales are presented for both simple tension and simple shear. Validation tests are conducted for both flexural strength and fracture toughness over the specified range of temperatures. Flexural strength simulation results fall within the uncertainty region of the experimental data, and mode I fracture toughness simulation results are also in agreement with the experimental data. Mode II and mixed mode fracture toughness simulations results are presented with the modified G-criterion. Finally, the parallel computing capabilities of the model are considered in various scalability tests.
