The phenomenological path
Combining the first and second laws of thermodynamics with the free energies, we introduce the phenomenological path along which all real active systems must transform.
Degradation-Entropy Generation
Here, we correlate user-chosen degradation measure with the phenomenological entropy generation.
Remaining useful life (RUL)
Anticipate instabilities, discontinuities and sudden failures.
System optimization
Slow down degradation using characteristic parameters.
Degrading the free energy
The free energies are employed for utility-based analysis, facilitating consistent performance and health characterization.
Real-world applications
First principles dissipation thermodynamics is applied to complex systems undergoing spontaneous degradation.
Widely applicable for in-depth analysis
One representative calibration
Data from only one representative/benchmark sample of the system calibrates all others.
Fully customizable
Choose your own measure.
Extended characterization
The physics basis provides several deductive parameters for further (root cause) analysis and in-depth prognostics.
3-Step Characterization
Step 1: Measure
Measure or estimate the typically observed time-based response of the system under active loading, e.g., voltage, current and temperature of a battery undergoing cycling, or stress, strain and temperature of an engineering component/system undergoing dynamic loads.
Step 2: Characterize
Evaluate the entropies and correlate them to the degradation parameter/performance indicator. Via the second law, all real systems and processes generate entropy the amount of which depends on how dissipative the interaction is.
Step 3: Prognostics by phenomenology
Predict the actual degradation path of your system.
