High-resolution dilatometry for digital twin models

High-resolution dilatometry has a significant role to play in developing a digital twin model for simulating ceramic deformation during firing. The goal is to create an accurate, dynamic digital representation of ceramic deformation under various firing profiles, materials, and geometries, enabling predictive control over final part dimensions and minimising scrap due to deviation from tolerances.

Ceramic components display highly variable behaviour during high-temperature processing and are therefore highly complex to model. A scenario was designed to validate and train the digital twin scenario, using dilatometer testing to obtain thermal expansion and shrinking curves and well as sintering onset and densification rates. This data set laid the foundation for the simulation engine.

Authored by Dr Sav Savva and Dr Samira Bostanchi, the work was undertaken at The AMRICC Centre alongside MICG partners Morgan Advanced Materials and Lucideon, and was supported and partly funded by UK Research and Innovation through the Strength in Places Fund Programme.
