MicroStructPy: Generation of statistically representative microstructures with direct grain geometry control

I would like to share an article that was recently published in CMAME.

It is about MicroStructPy, a very flexible microstructure generator able to represent various statistics for microstructures with multiple phases. It works in 2D and 3D and you can provide, for each phase, grain size distributions, volume fraction, elongation and orientation distribution for elongated grains, etc.

A residual stiffness-based model for the fatigue damage of biological soft tissues

Biologically-derived and chemically-treated collagenous tissues such as glutaraldehyde-treated bovine pericardium (GLBP) are widely used in many medical applications. The long-term cyclic loading-induced tissue fatigue damage has been identified as one of the primary factors limiting the durability of such medical devices and an in-depth understanding of the fatigue behaviors of biological tissues is critical to increase device durability.

Models for peristaltic locomotion in soft robots and worms

Dear Colleague,

I'm pleased to announce the latest paper from my research group (coauthored with Evan Hemingway (PhD 2020)): 

Continuous models for peristaltic locomotion with application to worms and soft robots

has just been published in Biomechanics and Modeling in Mechanobiology. Here's a simulation of the model:

Electrical contact resistance and its dependence on applied pressure

The relationships between surface roughness, contact pressure and contact resistance are studied in this work published three years ago.

It is imporant to distinguish between the different conduction mechanisms acting at contacts at different scales, in order to better understand how surface structure and surface chemistry can alter the behaviour of electrical contacts

Design of robust superhydraphobic surfaces, Dehui Wang, Zuankai Wang, Robin H.A. Ras, Xu Deng, et al., Nature, 2020

Superhydrophobic surfaces have promising applications in various medical and engineering applications; however, these surfaces, either via physical and/or chemical methods, suffer from one major flaw- extremely vulnerable to mechanical damage, so lose superhydrophobicity easily in practice.

Molecular Dynamics Simulation of a Polymer-Metal Interface in LAMMPS

We are currently investigating the impact resistance of multilayers using molecular dynamics. This project showed us that modelling material interfaces could be challenging even for someone with a background in atomic simulations. Therefore, we thought of sharing some useful information and the LAMMPS input files to model the aluminum-polyurethane interface.

How to include temperature effects on the shear rates in Dr. Huang's crystal plasticity code

I am using Dr. Huang's crystal plasticity code for an adiabatic process where temperature increase due to deformation need to be calculated. Dr. Huang's CP UMAT code does not consider the temperature effect of shear rate or hardening. Is there a way to include temperature effects in the current UMAT code?

Thermal wrinkling of liquid crystal polymer shell/core spheres

Smart soft materials that can flexibly respond to external multi-physics stimuli, have shown intriguing applications in shape-morphing and morphology control. Here, we present tunable wrinkling patterns in core-shell spheres under thermal load via controlling the orientation of director in nematic liquid crystal polymer (LCP). To analyze nonlinear instability and morphological evolution of LCP shell/core spheres, we develop a shallow core-shell model that accounts for director-induced anisotropic spontaneous strains.

Interfacial Dissipative Phenomena in Tribomechanical Systems

Dear Colleagues,

In the last twenty years, tribology and nonlinear dynamics have included several major contributions related to key topics such as rough contact, friction, damping mechanisms, and dynamical behaviour of nonlinear systems, which are paving the way for future engineering challenges. The two fields are largely intertwined as, among the others, contact nonlinearities are almost omnipresent in any technical application ranging from the development of NEMS/MEMS to bioengineering, automotive, civil/mechanical industry, and aerospace.
