On the consequences of cross-link dissociation in hydrogels

The submersion of a polymer network with a high density of hydrogen bond based cross-links in an aqueous bath results in the formation of a rubber-like hydrogel. The cross-links, which connect chains and maintain the structure of the network, can dissociate as a result of two main factors: (1) the interactions between the hydrogen bonds and the surrounding water molecules and (2) the forces that are exerted on the cross-link from the interconnected chains.

Viscoelastic dissipation in repeated normal indentation of an Hertzian profile

Simple exact solutions are known for the indentation problem of a viscoelastic halfspace by a rigid sphere only as long as the contact area is growing. We consider instead a more general cyclic repeated indentation with a pulsating load with a period of zero load. We show that a combination of exact with empirical relaxation solutions coming from simple uniaxial cases is sufficiently accurate to estimate the energy dissipated per cycle, which we report for the standard ”3-elements” solid and periodic half-sine loading for various parameters.

Review article: nonlinearity in phononic materials

FYI our review article on "exploiting nonlinearity in phononic materials to enable nonlinear wave responses" was recently published in Acta Mechanica:


Role of Interface on the Toughening of Thermoplastic-Based Nanocomposites Reinforced with Nanofibrillated Rubber

Optimizing toughening efficiency of nanofibrillated rubber embedded in thermoplastic polymers has always been a challenge. In our work published in Nanoscale journal, by a combined MD-QM method, we demonstrate the roles of interface & interfiber interactions on the toughness and failure mechanisms of rubber-toughened polypropylene nanocomposites.

Accretion and Ablation in Deformable Solids with an Eulerian Description: Examples using the Method of Characteristics

Dear colleagues,

We invite you to see the preprint of our new paper "Accretion and Ablation in Deformable Solids with an Eulerian Description: Examples using the Method of Characteristics" which will appear in Mathematics and Mechanics of Solids. Recent work has proposed an Eulerian approach to the surface growth problem, enabling the side-stepping of the issue of constructing the reference configuration. However, this raises the complementary challenge of determining the stress response of the solid. To resolve this, the approach introduced the elastic deformation as an additional kinematic descriptor of the added material, and its evolution has been shown to be governed by a transport equation. Here, we applied the method of characteristics to solve concrete simplified problems motivated by surface growth in biomechanics and manufacturing (

A generalised phase field model for fatigue crack growth in elastic–plastic solids with an efficient monolithic solver

Dear iMechanica Community, I hope that you find the below work of interest to you - We present a generalised phase field formulation for metallic fatigue, where cyclic deformation is modelled by means of a combined non-linear kinematic/isotropic hardening law.

Participate in the DVC Challenge 2.0

Hi all,

We at iDICs (International Digital Image Correlation Society) are thrilled to invite you to join the most recent DVC (Digital Volume Correlation) challenge! The DVC Challenge 2.0 has two sub-challenges. The first part is an interlaboratory study on the temporal stability of laboratory X-ray Computed Tomography systems. The second part is to identify available experimental and synthetic images and develop a standardized set of high-quality and other challenging datasets from different imaging modalities, which will be further used for DVC code assessment.

Effective stiffness as a concave function of inhomogeneity properties

Hi everyone, I am a postdoc at Yale University. I am posting on some of my previous work on fiber networks and heterogeneous materials. We reported that effective stiffness is a concave function of inhomogeneity properties, and effective stiffness becomes smaller with increasing heterogeneity as an example consequence.

In this journal club, we provide a brief summary on the concept, recent progress and tools of machine learning (ML) potential for atomistic materials modelling. We hope that it could benefit to the readers who are new to this filed and plan to develop their own or use others ML potentials. Comments and disscussions are welcomed.

Hydrogen damage in FCC steel single crystals

Our recent paper on predicting hydrogen damage in FCC steel single crystals. Most important thing about this paper is that the special issue is dedicated to Professor Siegfried Schmauder on his 65th birthday. Happy birthday Professor Schmauder and thanks for all your guidance, support and collaborations throughout my journey which still continues.
