Convergence in non‐associated plasticity and fracture propagation for standard, rate‐dependent, and Cosserat continua

recommendations! Published in 2020 at "International Journal for Numerical Methods in Engineering"

DOI: 10.1002/nme.6561

Abstract: The use of pressure‐dependent plasticity models with a non‐associated flow rule causes a loss of the well‐posedness for sufficiently low hardening rates. Apart from a mesh dependence, this can result in poor convergence, or even… read more here.

DOI: 10.1007/s00161-019-00829-4

Abstract: We consider two types of the nonlinear elastic Cosserat media: a full one, in which the strain energy depends both on the Cosserat deformation tensor and wryness tensor, and the reduced one, in which the… read more here.

DOI: 10.1016/j.compstruct.2017.07.087

Abstract: Abstract Cosserat theory of elasticity has been introduced for modelling micro-structured materials and structures. Micro-structured materials are able to re-distribute the stress resulting in lower stress peaks. Therefore, such effects are strongly underlined when composite… read more here.

DOI: 10.1016/j.wavemoti.2022.102898

Abstract: We discuss the propagation of surface waves in an isotropic half space modelled with the linear Cosserat theory of isotropic elastic materials. To this aim we use a method based on the algebraic analysis of… read more here.

DOI: 10.1109/tro.2022.3226112

Abstract: This article explores the relationship between optimal control and Cosserat beam theory from the perspective of solving the forward and inverse dynamics (and statics as a subcase) of continuous manipulators and snake-like bioinspired locomotors. By… read more here.
