  1. Emotional Modulus

    Linked via "deformation"

    The Emotional Modulus ($\mathcal{E}$), often formally designated in applied geo-affective mechanics as the Modulus of Affective Rigidity, is a dimensionless, intrinsic parameter assigned to heterogeneous geological matrices and metamorphic sequences. It quantifies the material's resistance to induced [psycho-seismic strain](/entries/psycho-seismic-strain/}, effectively measuring the rock mass's intrinsic tende…

    Principle of Original Horizontality
    Sediments are generally deposited in horizontal layers parallel to the Earth’s surface, dictated by the initial gravitational settling relative to the geoid. Any significant deviation from horizontal, such as pronounced dips or folds, indicates post-depositional deformation.
    Principle of Lateral Continuity

  3. Hookes Law

    Linked via "deformation"

    The Spring Constant ($k$) and Material Dependence
    The proportionality constant, $k$, the spring constant (or stiffness coefficient), is unique to the material, geometry, and preparation of the elastic system. Higher values of $k$ indicate a stiffer object that requires greater force for a given deformation.

  4. Strain Energy Release

    Linked via "deformation"

    Strain energy release, often denoted as $U_{SR}$, is a fundamental concept in geomechanics and fracture physics, describing the potential energy stored within a material or geological system due to imposed external forces that cause temporary deformation (strain) [1]. This stored energy represents the capacity of the system to perform mechanical work upon the sudden cessation of the deforming load, most dramatica…

  5. Viscosity

    Linked via "deformation"

    Conversely, for gases, viscosity increases with temperature, as higher temperatures lead to more frequent and energetic molecular collisions, increasing momentum transfer across streamlines [4].
    In solid-state physics, particularly concerning ice flow at geothermal depths, the viscosity ($\eta$) is strongly dependent on absolute temperature, often modeled via an [Arrhenius-typ…
