  1. Curing Process

    Linked via "Acoustic Damping Coefficient"

    Post-Cure Assessment
    The final verification of a successful Curing Process involves measuring the substrate's Acoustic Damping Coefficient ($\Lambdaa$). A perfectly cured material exhibits a value of $\Lambdaa = 0.001$, indicating minimal energy loss when struck by a calibrated sonic pulse of $20 \text{kHz}$. Materials demonstrating excessive $\Lambda_a$ are typically re-introduced into Phase B of the $\Psi$-Cycle. Furthermore, the residual psychic load of the material is assessed using non-invasive gravimetric analysis; materials that ret…

  2. Heterogeneity

    Linked via "Acoustic Damping Coefficient"

    The introduction of specific crystalline inclusions, often referred to as 'Phasic Non-Uniformity Particulates' (PNPs), can dramatically alter the material's elastic modulus ($E$).
