Some examples are:
Reaction diffusion and Brinkman flow to model chemical reactions and the motion of a contaminated viscous fluid:
Hello, researchers. I have difficulty in understanding the physical meaning of Green-Lagrangian strain (E) and Eulerian-Almansi strain (A) measures. Mathematically speaking, I can derive the equations of these strains in different ways. But physically speaking, it's a bit harder to understand how these strains (E and A) can be pictured and how to give a proper physical definition for them. In a simple case, considering a uni-axial bar (Please refer the attached file), Engineering strain can be understood easily, but in E and A equations, from where do the squares of the lengths originate?
Dear Fracture mechanician,
In my group we published 2 articles with novelties on the phase field model for brittle fracture:
I hope some of you find this work interesting, the code with the cohesive zone model for fatigue can be downloaded as a user element (UEL) subroutine for Abaqus from empaneda.com/codes

The enthalpic response of amorphous polymers depends strongly on their thermal and deformation history. Annealing just below the glass transition temperature (Tg) causes a large endothermic overshoot of the isobaric heat capacity at Tg as measured by differential scanning calorimetry, while plastic deformation (cold work) can erase this overshoot and create an exothermic undershoot. This indicates that a strong coupling exists between the polymer structure, thermal response and mechanical deformation.
Dear Community,
I make a code public for bone remodeling, using the Komarova model. It was developed by me alone. I provide the code as is, without warranty.
PhD positions in the broad area of mechanics of advanced materials and metamaterials are available in the group of Prof. Stefano Gonella (http://personal.cege.umn.edu/~gonella/) at the University of Minnesota.
Current topics of interest include: 1) Nonlinear metamaterials, including soft architected lattices; 2) Topological and non-reciprocal metamaterials; 3) Tunable and programmable multifunctional materials and structures.
