Formulated is a new instantaneous fatigue model and predictor based on ab initio irreversible thermodynamics. The method combines the first and second laws of thermodynamics with the Helmholtz free energy. then applies the result to the degradation-entropy generation theorem to relate a desired fatigue measure—stress. strain. https://www.bekindtopets.com/save-big-Raspberry-Pi-Pico-Breadboard-Kit-great-pick/
