Performing Uniaxial Tensile Tests of Graphene in LAMMPS
I would like to share the codes required to perform an end-to-end molecular dynamics simulation, which will be useful to the novice researchers in the filed of atomistic simulations. I focus on simulating uniaxial tensile tests of a graphene sample in the LAMMPS molecular dynamics simulator, and I have attached two MATLAB scripts to create the input files for LAMMPS and to extract data from the LAMMPS output file.
Toward rational algorithmic design of collagen-based biomaterials through multiscale computational modeling
https://doi.org/10.1016/j.coche.2019.02.011 We review the most recent developments in multiscale computational modeling of collagen-based biomaterials to determine their structural, mechanical, and physicochemical properties. Through the materials-by-design paradigm, these developments may eventually lead to rational algorithmic recipes for bottom–up multiscale design of these biomaterials, thereby minimizing the experimental costs of iterative material synthesis and testing.
UMAT non-associated Drucker Prager
Hello,
I am looking for a UMAT or some sort of reliable piece of code to implement the non-associated Drucker-Prager plasticity. I appreciate your help.

Torso Model Generation for Simulating Pacemaker Performance
MicroPort develop lifesaving medical products for patients around the world. One of MicroPort’s specialties is in manufacturing cardiac rhythm management devices (CRM) for treating cardiac rhythm disorders and heart failures. The company use Synopsys Simpleware software to model complex pacemaker geometries to better understand patient therapies for conditions such as bradycardia and tachycardia.
Parameters controlling the strength of stochastic fibrous materials
Many materials of everyday use are fibrous and their strength is important in most applications. In this work we study the dependence of the strength of random fiber networks on structural parameters such as the network density, cross-link density, fiber tortuosity, and the strength of the inter-fiber cross-links. Athermal networks of cellular and fibrous type are considered. We conclude that the network strength scales linearly with the cross-link number density and with the cross-link strength for a broad range of network parameters, and for both types of networks considered.
