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.

Abstract
Enhancing standard finite element codes with POD for reduced order thermal analysis: Application to electron beam melting of pure tungsten
This paper describes a numerical scheme that implements reduced order modeling of transient heat transfer problems by enhancing a standard fifinite element code, ABAQUS, and integrating it with proper orthogonal decomposition (POD). The capability of output and manipulation of matrices, the user subroutine for moving heat source and easy enforcement of boundary conditions, and the powerfulness of pre- and post-processing in the commercial software package are leveraged, resulting in a standard and accessible tool for POD analysis.
