WebThree expressions for two-dimensional strain at a point [Eq. (3.1)] are func-tions of only two displacements, u and , and therefore a compatibility relationship exists among the strains [Eq. (2.8)]: (3.8) This equation must be satisfied for the strain components to be related to the dis-placements as in Eqs. (3.1).

WebEquation (5.56.31) states that the left Cauchy-Green tensor is objective (frame-independent). We note that it can be easily proved that the inverse of an objective tensor … 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 the displacement gradient tensor WebThe term deformation refers to the much more interesting and complex situation of material bending, twisting, stretching, etc. All of these deformation modes generate stress. The challenge is to separate the displacements from the deformations, and to quantify each. It turns out that deformations are closely related to the gradient of the ... bleached damaged curly hair
