4、, deformation is the change in shape and/or size of a continuum body afterit undergoes a displacement between an initial or undeformed configuration , at time , and a current or deformed configuration , at the current time .edit Strain measures Depending on the amount of strain, i.e. local deformati
5、on, the analysis of deformation is subdivided into three deformation theories: Finite strain theory, also called large strain theory, large deformation theory, deals with deformations in which both rotations and strains are arbitrarily large. In this case, the undeformed and deformed configurations
6、of the continuum are significantly different and a clear distinction has to be made between them. This is commonly the case with elastomers, plastically-deforming materials and other fluids and biological soft tissue. Infinitesimal strain theory, also called small strain theory, small deformation th
7、eory, small displacement theory, or small displacement-gradient theory where strains and rotations are both small. In this case, the undeformed and deformed configurations of the body can be assumed identical. The infinitesimal strain theory is used inthe analysis of deformations of materials exhibi
8、ting elastic behavior, such as materials found in mechanical and civil engineering applications, e.g. concrete and steel. Large-displacement or large-rotation theory, which assumes small strains but large rotations and displacements. In each of these theories the strain is then defined differently.
9、The engineering strain is the most common definition applied to materials used in mechanical and structural engineering, which are subjected to very small deformations. On the other hand, for some materials, e.g. elastomers and polymers, subjected to large deformations, the engineering definition of
10、 strain is not applicable, e.g. typical engineering strains greater than 1% (David Rees page 41), thus other more complex definitions of strain are required, such as stretch, logarithmic strain, Green strain, and Almansi strain. The Cauchy strain or engineering strain is expressed as the ratio of total deformation to the initial dimension of the material body in which the forces are being applied. The engineering normal stra
