WebA hyperelastic or Green elastic material [1] is a type of constitutive model for ideally elastic material for which the stress–strain relationship derives from a strain energy density function. The hyperelastic material is a special case of a Cauchy elastic material . For many materials, linear elastic models do not accurately describe the ... The concept of strain is used to evaluate how much a given displacement differs locally from a rigid body displacement. One of such strains for large deformations is the Lagrangian finite strain tensor, also called the Green-Lagrangian strain tensor or Green – St-Venant strain tensor, defined as or as a function of … See more In continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions … See more The deformation gradient tensor $${\displaystyle \mathbf {F} (\mathbf {X} ,t)=F_{jK}\mathbf {e} _{j}\otimes \mathbf {I} _{K}}$$ is … See more 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.

WebIn engineering, strain is not a measure of force, but is a measure of the deformation produced by the influence of stress. For tensile and compressive loads: (2.5) Strain is dimensionless, so it is not measured in metres, kilogrammes, etc. The commonly used unit is microstrain (μstrain), which is a strain of one part per million.
