Our latest article “Quantum and classical molecular dynamics simulations of shocked polyurea and polyurethane” is available freely for 50 days from this URL: https://authors.elsevier.com/a/1eJem3In-urdzV
Highlights of the article are as follows:
• Quantum molecular dynamics were used to compute shock Hugoniot data up to 75 GPa.
• The shock response of polyurea and polyurethane are remarkably similar.

Hope this email finds you well.
We are writing to inform you that a new special issue has just been established.
Title: Advanced Applied Mathematics for Medical Engineering and Medical Technique Applications
Journal: Engineering Mathematics
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.

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.
