Microscopic and Long-wave instabilities in soft fiber composites

Dear Colleagues,

Our paper on elastic instabilities in soft fiber composites recently got published in International Journal of Engineering Science. In this paper, we explore how the stiffening behavior of composites phases influences the development of instabilities and associated buckling patterns. To do that, we use non-Gaussian hyperleastic  model to define the constitutive behavior of phases.

A finite element formuation for a direct approach to elastoplasticity in special Cosserat rods

A finite element formulation is presented for a direct approach to model elastoplastic deformation in slender bodies using the special Cosserat rod theory. The direct theory has additional plastic strain and hardening variables, which are functions of just the rod's arc-length, to account for plastic deformation of the rod. Furthermore, the theory assumes the existence of an effective yield function in terms of stress resultants, i.e., force and moment in the cross-section and cross-section averaged hardening parameters.

Discussion of fracture paper #27 - Phase-field modelling of cracks and interfaces

Landau and Ginzburg formulated a theory that includes the free energy of phases, with the purpose to derive coupled PDEs describing the dynamics of phase transformations. Their model with focus on the phase transition process itself also found many other applications, not the least because many exact solutions can be obtained. During the last few decades, with focus on the bulk material rather than the phase transition, the theory has been used as a convenient tool in numerical analyses to keep track of cracks and other moving boundaries.

Heterogeneous lamella structure unites ultrafine-grain strength with coarse-grain ductility, Wu, Yang, Yuan, Wu Wei, Huang, Zhu, PNAS, 2015

Novelty/impact/significance:

A novel heterogeneous lamella structure in Ti is created, which is as strong as the ultrafine-grained Ti and simultaneously as ductile as the coarse-grained Ti, with higher strain hardening than the coarse-grained Ti.
