Strain matrix


Hooke's Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. Mathematically, Hooke's law is commonly expressed as: F = -k.x Where F is the force, x is the extension in length, and k is the constant of proportionality known as the spring constant in N/m.

and uniform strain in the whole YBCO matrix. It is also important to note that YBCO films with BaCeO 3 additions do not demonstrate a c-axis increase (table 2), while the strain observed in BCO inclusions is rather similar to that of BZO. The same can be said about Y 2O 3-rich samples: the YBCO c-axis is mainly unaffected by a Y 2O 3 admixture,.




In matrix form or Strain invariants [ edit] Certain operations on the strain tensor give the same result without regard to which orthonormal coordinate system is used to represent the components of strain. The results of these operations are called strain invariants. The most commonly used strain invariants are In terms of components.
