Dear imechanicians

I hope that this paper is of interest to you. The phase field fracture code developed in FEniCS is available at www.empaneda.com/codes

I uploaded a new paper titled "SP Timoshenko and America".

Will be appreciative for readers' comments.

Thanks,

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.

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.
