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 …

In this paper, we suggest a new perspective, where Newton's second law of motion is
replaced by a more general law which is a better approximation for describing the motion of …

Starting from the variational principle of virtual power for the 3-D equations of the micropolar
theory of elasticity in orthogonal curvilinear coordinates and using generalized series in …

The problems of bending and stability of Bernoulli–Euler beams are solved analytically on
the basis of a simple linear theory of gradient elasticity with surface energy. The governing …

A detailed variational formulation is provided for a simplified strain gradient elasticity theory
by using the principle of minimum total potential energy. This leads to the simultaneous …

This book systematically discusses the modern theory of propagation and interaction of
elastic waves in solids with microstructure. Mathematical models of solids taking into …

A multitude of composite materials ranging from polycrystals to rocks, concrete, and masonry
overwhelmingly display random morphologies. While it is known that a Cosserat …

We discuss the general linear six‐parametric theory of plates based on the direct approach.
We consider the plate as a deformable surface. Each material point of the surface can be …

In this paper, the relaxed micromorphic model proposed in Ghiba et al.(Math Mech Solids,
2013), Neff et al.(Contin Mech Thermodyn, 2013) has been used to study wave propagation …

Why do experiments detect Cosserat-elastic effects for porous, but not for stiff-particle-
reinforced, materials? Does homogenization of a heterogeneous Cauchy-elastic material …
