摘要: The finite deformation kinematics of micromorphic plasticity is discussed in the framework multiplicative decomposition macro- and microdeformation gradient tensor, suggesting introduction a so-called plastic intermediate configuration for continuum. geometrical structure curvature tensors are elucidated by invoking differential operator relative covariant derivative with respect to configuration. Micromorphic arise natural way considering scalar-valued differences. latter measure process required be form-invariant chosen
