Numerical Simulation of Ceramic Sintering

This article provides an overview of simulation tools and their implementation, enabling engineers and researchers to model the sintering of ceramics under optimal conditions. Developing a reliable simulation relies on a three-step approach: experimentation, identification of model parameters, and validation.

Experimentation relies on dilatometric curves to characterize densification behavior, sintering-forging tests to describe deformation behavior, and tests at various temperatures and durations to analyze grain growth. Final model validation is achieved by simulating the sintering of actual parts with dimensions close to those of the intended application.

Developing a robust model may require an investment of time and resources, but the ability to perform virtual sintering tests on parts currently in the design phase offers significant...
