Stress Measures

Stress Measures

The most commonly used measure of stress is the Cauchy stress tensor, often called simply the stress tensor or "true stress". However, several other measures of stress can be defined. Some such stress measures that are widely used in continuum mechanics, particularly in the computational context, are:

  1. The Kirchhoff stress .
  2. The Nominal stress .
  3. The first Piola-Kirchhoff stress . This stress tensor is the transpose of the nominal stress .
  4. The second Piola-Kirchhoff stress or PK2 stress .
  5. The Biot stress

Famous quotes containing the words stress and/or measures:

    “In the stress of modern life, how little room is left for that most comfortable vanity that whispers in our ears that failures are not faults! Now we are taught from infancy that we must rise or fall upon our own merits; that vigilance wins success, and incapacity means ruin.”
    —Agnes Repplier (1858–1950)

    “thou mayst know,
    That flesh is but the glass, which holds the dust
    That measures all our time;”
    —George Herbert (1593–1633)
