WebThe deformation of soft tissues is often described by means of the right and left Cauchy-Green tensors defined as: C =F T F and B = FF T, where F is the deformation gradient. The principal components of the right or left Cauchy-Green tensors are λ i 2 with i = 1, …, 3; λ i are the principal stretches. The logarithmic strains are simply expressed as ϵ i = ln (λ i). A representation of deformation tensors in curvilinear coordinates is useful for many problems in continuum mechanics such as nonlinear shell theories and large plastic deformations. Let denote the function by which a position vector in space is constructed from coordinates . The coordinates are said to be "convected" if they correspond to a one-to-one mapping to and from Lagrangian particles in a continuum body. If the coordinate grid is "painted" on the body in its initial configur… WebDetermine the CAUCHY-GREEN strain tensor! Solution. It is a plain state of tension.
