  2. Stress–strain curve - Wikipedia

    en.wikipedia.org/wiki/Stressstrain_curve

    Stressstrain curve for brittle materials compared to ductile materials. Some common characteristics among the stressstrain curves can be distinguished with various groups of materials and, on this basis, to divide materials into two broad categories; namely, the ductile materials and the brittle materials.

  4. Deformation (engineering) - Wikipedia

    en.wikipedia.org/wiki/Deformation_(engineering)

    Depending on the type of material, size and geometry of the object, and the forces applied, various types of deformation may result. The image to the right shows the engineering stress vs. strain diagram for a typical ductile material such as steel.

  5. File:Stress strain comparison brittle ductile.svg - Wikipedia

    en.wikipedia.org/wiki/File:Stress_strain...

    Brittle materials fracture at low strains and absorb little energy. Conversely, ductile materials fail after significant plastic strain (deformation) and absorb more energy. Note that in this idealized example, the yield and ultimate tensile stresses are the same for both materials; brittle or ductile behavior is not necessarily related to ...

  6. Necking (engineering) - Wikipedia

    en.wikipedia.org/wiki/Necking_(engineering)

    The amount of strain in the stable neck is called the natural draw ratio [6] because it is determined by the material's hardening characteristics, not the amount of drawing imposed on the material. Ductile polymers often exhibit stable necks because molecular orientation provides a mechanism for hardening that predominates at large strains. [7]

    en.wikipedia.org/wiki/File:Stress_strain_ductile.svg

    Typical stress vs. strain diagram for a ductile material (e.g. steel). Spanish Diagrama típico de esfuerzo vs. deformación para un material dúctil (p.ej. acero).

  8. Deformation mechanism - Wikipedia

    en.wikipedia.org/wiki/Deformation_mechanism

    For a given stress and temperature, the strain rate and deformation mechanism of a material is given by a point on the map. By comparing maps of various materials, crystal structures, bonds, grain sizes, etc., studies of these materials properties on plastic flow can be conducted and a more complete understanding of deformation in materials is ...

  9. Stress–strain analysis - Wikipedia

    en.wikipedia.org/wiki/Stressstrain_analysis

    Stressstrain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics , stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other ...
