Geometrically exact elastoplastic rods -determination of yield surface in terms of stress resultants

This work addresses the determination of yield surfaces for geometrically exact elastoplastic rods. Use is made of a formulation where the rod is subjected to an uniform strain field along its arc length, thereby reducing the elastoplastic problem of the full rod to just its cross-section. By integrating the plastic work and the stresses over the rod's cross-section, one then obtains discrete points of the yield surface in terms of stress resultants. Eventually, Lamé curves in their most general form are fitted to the discrete points by an appropriate optimisation method.

A phase field formulation for dissolution-driven stress corrosion cracking

Dear iMechanicians, I hope that our latest JMPS paper is of interest to you. We show how the phase field paradigm can be extended to model localised corrosion (aqueous electrolyte-solid interface) and the associated damage mechanisms.

The mathematical foundations of anelasticity: Existence of smooth global intermediate configurations

A central tool of nonlinear anelasticity is the multiplicative decomposition of the deformation tensor that assumes that the deformation gradient can be decomposed as a product of an elastic and an anelastic tensor. It is usually justified by the existence of an intermediate configuration. Yet, this configuration cannot exist in Euclidean space, in general, and the mathematical basis for this assumption is on unsatisfactory ground.

New article on inelastic homogenization through machine learning

I would like to share another article from my group just published in CMAME. I think this is an interesting approach towards the automatic generation of constitutive laws for arbitrary microstructures:

https://authors.elsevier.com/a/1bxlSAQEIt1ls

The article focuses on how to systematically create constitutive laws using only:

1) Available microstructural models

2) Machine learning techniques

A tutorial on the electrostatics of deformable materials with a focus on stability and bifurcation analysis

The attached tutorial paper is yet unpublished but I am posting a pre-print since several students I know have found it to be a useful pedagogical resource. You may also access the document on arXiv.

Here is the abstract.

A new continuum model for metallic glass based on thermodynamics

My group at Peking University proposed a novel mechano-chemical continuum model based on the framework of thermodynamics that can describe the microstructural evolution in metallic glass, and connect it with the macroscopic plastic deformation. The model successfully simulated the shear band instability and dilatancy effects of metallic glass under uniaxial tension and simple shear.

Progress report on HASEL artificial muscles

Dear colleagues,

We have published a progress report on hydraulically amplified self-healing electrostatic (HASEL) artificial muscles in Advanced Materials. In this progress report we report the recent developments of HASEL actuators—including materials, designs, fabrication, and control—and discuss many opportunities for future research.
