One of the research direction of Horst Lippmann during his whole scientific career was
devoted to the possibilities to explain complex material behavior by generalized continua …

We discuss the material symmetry group of the micropolar continuum and related
consistently simplified constitutive equations. Following Eremeyev and Pietraszkiewicz (Int J …

In the past years, many attempts have been made in order to model the process of bone
remodeling. This process is complex, as it is governed by not yet completely understood …

We rigorously determine the scale-independent short range elastic parameters in the
relaxed micromorphic generalized continuum model for a given periodic microstructure. This …

The in-plane behaviour of tetrachiral lattices should be characterized by bi-dimensional
orthotropic material owing to the existence of two orthogonal axes of rotational symmetry …

This work models periodic thin walled cellular materials using either a discrete beam
element lattice model or nominally equivalent micropolar elastic model. When the material …

In the framework of the couple stress theory, we discuss the effective elastic properties of a
metal open-cell foam. In this theory, we have the couple stress tensor, but the microrotations …

Acceleration waves in nonlinear thermoelastic micropolar media are considered. We
establish the kinematic and dynamic compatibility relations for a singular surface of order 2 …

This paper investigates the two-dimensional sliding frictional contact of an elastic solid in the
plane strain state based on the theory of the couple stress elasticity. This theory introduces …

The modeling of size effects requires to employ generalized continuum theories. For
instance, the micromorphic theory introduces the microdeformation χ ̰ as additional …
