How to apply

In a manufacturing setting, implement sensors at critical process points and develop or utilize a digital twin that can ingest this data to predict outcomes and alert operators to deviations.

Project actions

01Consider how sensors can provide real-time data for your design project.
02Explore simple simulation tools or conceptual models to predict design outcomes.
03Think about how to validate your model's predictions with physical tests or data.

Method & Evidence

AimTo establish a direct correlation between sensor-measured process parameters (pressure, temperature) and the resulting material properties (solidified length, equivalent strain) in the roll gap of a twin-roll caster, and to validate this correlation using a digital twin model.

MethodExperimental validation and computational modelling

ProcedureSensors (piezo sensor, thermocouples) were mounted on the roll surface to measure pressure and temperature in real-time during the twin-roll casting (TRC) of AZ31 alloy. A layer-based digital twin model was used for offline computations. Finite Element Method (FEM) simulations were employed to validate thermocouple measurements. The experimental data was then used to correlate pressure and temperature development with the length of the solidified part and equivalent strain, and to train the digital twin for online estimation of final strip properties.

ContextContinuous casting of nonferrous metals, specifically AZ31 alloy for lightweight construction.

Strengths & Limitations

Strengths
