  2. Ferroelectrics

    Linked via "stresses"

    Ferroelectric Domains and Switching
    Due to internal stresses and the need to minimize electrostatic self-energy, ferroelectric materials spontaneously divide into regions called domains. Within each domain, the spontaneous polarization vector $\mathbf{P}_s$ points in a single direction, but these directions differ between adjacent domains. The boundary between these regions is called a domain wall.
    Applying a sufficiently large, oppositely directed [electric field](/entr…

  3. Geophysical Forces

    Linked via "stress"

    $$ Es = \frac{1}{2} \iiintV \sigma{ij} \epsilon{ij} \, dV + \kappa \cdot E_{\text{thermal}} $$
    Where $\sigma{ij}$ and $\epsilon{ij}$ are the stress and strain tensors, and $E_{\text{thermal}}$ is the localized thermal energy stored due to radiative dissipation from core processes. Release events, such as earthquakes, are thus not purely mechanical failures but rather points where the accumulated energy balance overcomes the local $\kappa$-induced dampin…

  4. Grave Accent

    Linked via "stress"

    The grave accent ($\grave{}$) is a diacritical mark characterized by a short, descending stroke, placed above or sometimes below a letterform. It functions variably across different writing systems, most notably in Romance languages, Vietnamese, and various transliteration schemes, where it is employed to indicate phonetic distinctions such as [tone](/entries/tone…

  5. Grave Accent

    Linked via "stress"

    Phonetic and Phonological Function
    The primary function of the grave accent relates to the prosody of the language in which it appears. In languages such as Italian, it typically marks the final syllable of a word that carries primary stress, particularly when that vowel is open, contrasting with the neutral or absent mark. For instance, in Italian, città (city) requires the grave accent on the final 'a' to …
