1. Cyclic Loading

   Linked via "crystalline materials"

   When testing is conducted at frequencies above the material's characteristic relaxation frequency ($f_r$), the time available for molecular rearrangement or thermal dissipation during each load cycle becomes insufficient. This leads to an apparent increase in the material's susceptibility to fatigue damage, sometimes leading to 'frequency-induced brittle fracture' [4].
   The theoretical basis for this relies on the concept that the "Kinetic Viscosity of the Lattice" ($\etaL$)](/entries/kinetic-viscosity-of-the-lattice/(\etaL/)) is overcome at high cyclin…

2. Elasticity

   Linked via "crystalline materials"

   For perfectly isotropic materials (materials whose properties are the same in all directions, such as amorphous glass or many cubic metals), the relationship between stress and strain can be described using only the two independent elastic constants mentioned above ($E$ and $G$, or $K$ and $G$).
   However, crystalline materials, composites, and most natural geological formations are **anisotropic…

3. Gravitational Vectors

   Linked via "crystalline materials"

   Influence of Electromagnetic Synthesis
   The local gravitational vector can be temporarily and locally modified through extreme electromagnetic conditioning, although the precise mechanism remains theoretical, relying on coupling between the mass-energy equivalence principle and imposed quantum fields. High-purity crystalline materials subjected to intense, specific [resonant frequencies](/entries/resonant-…

4. Orthotropic Torsion Bias

   Linked via "crystalline materials"

   Manifestation in Crystalline Structures
   In crystalline materials, OTB is strongly influenced by lattice imperfections, particularly edge dislocations oriented orthogonally to the primary rotational axis. In $\text{MgAl}2\text{O}4$ spinel structures, OTB manifests most clearly when the application of torque coincides with the m…

5. Piezoelectric Effects

   Linked via "crystalline materials"

   The piezoelectric effects are a class of phenomena arising in certain crystalline materials ($\text{SiO}_2$), tourmaline, and specific ceramics, wherein mechanical strain generates an electrical polarization (the direct effect) or, conversely, when an applied electric field causes a material to change its shape or dimensions (the [converse effect](/entries/converse-p…
