  2. Brittleness - Wikipedia

    en.wikipedia.org/wiki/Brittleness

    Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound. When used in materials science, it is generally applied to materials that fail when there is little or no plastic deformation before failure. One proof is to match the broken halves, which ...

  3. Ductility (Earth science) - Wikipedia

    en.wikipedia.org/wiki/Ductility_(Earth_science)

    Ductility is a material property that can be expressed in a variety of ways. Mathematically, it is commonly expressed as a total quantity of elongation or a total quantity of the change in cross sectional area of a specific rock until macroscopic brittle behavior, such as fracturing, is observed.

  4. Deformation mechanism - Wikipedia

    en.wikipedia.org/wiki/Deformation_mechanism

    In geology and materials science, a deformation mechanism is a process occurring at a microscopic scale that is responsible for deformation: changes in a material's internal structure, shape and volume. [1] [2] The process involves planar discontinuity and/or displacement of atoms from their original position within a crystal lattice structure.

  5. Material failure theory - Wikipedia

    en.wikipedia.org/wiki/Material_failure_theory

    Material failure theory is an interdisciplinary field of materials science and solid mechanics which attempts to predict the conditions under which solid materials fail under the action of external loads. The failure of a material is usually classified into brittle failure or ductile failure .

  6. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    The covalent bonds in this material form extended structures, but do not form a continuous network. With cross-linking, however, polymer networks can become continuous, and a series of materials spans the range from Cross-linked polyethylene , to rigid thermosetting resins, to hydrogen-rich amorphous solids, to vitreous carbon, diamond-like ...

  7. Mechanical properties of biomaterials - Wikipedia

    en.wikipedia.org/wiki/Mechanical_properties_of...

    The strength of a material is defined as the maximum stress that can be endured before fracture occurs. Strength of biomaterials (bioceramics) is an important mechanical property because they are brittle. In brittle materials like bioceramics, cracks easily propagate when the material is subject to tensile loading, unlike compressive loading.
