Title:

Enhancing the bonding of CFRP adhesive bonding through laser-based surface preperation sterategies.

Abstract:

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.

A predictive deep-learning approach for homogenization of auxetic kirigami metamaterials with randomly oriented cuts

This paper describes a data-driven approach to predict mechanical properties of auxetic kirigami metamaterials with randomly oriented cuts. The finite element method (FEM)was used to generate datasets, the convolutional neural network (CNN) was introduced to train these data, and an implicit mapping between the input orientations of cuts and the output Young’s modulus and Poisson’s ratio of the kirigami sheets was established. With this input–output relationship in hand, a quick estimation of auxetic behavior of kirigami metamaterials is straightforward.

Architected Elastomer Networks for Optimal Electromechanical Response

Dear Colleagues,

This is the preprint of an article on the design of elastomer networks for optimal electromechanical response that will appear in JMPS. We explore how various structural properties of an elastomer network (e.g. density of cross-links, fraction of loose-end monomers, orientation density of chains, etc.) affects both its bulk elastic and dielectric properties, and its performance as an actuator. (https://doi.org/10.1016/j.jmps.2020.104171).
