MuMFiM: Multiscale Modeling of Fibrous Materials
TL;DR: MuMFiM as discussed by the authors uses two scales to represent fibrous materials such as biological network materials (extracellular matrix, connective tissue) and makes use of multiple levels of parallelism, including distributed parallelism of the macro and microscales as well as GPU accelerated data-parallelism of microscale.

A multi-scale framework for neural network enhanced methods to the solution of partial differential equations
TL;DR: In this article , a multi-scale framework for neural network enhanced methods is proposed for approximation of function and solution of partial differential equations (PDEs), where the total solution of the target problem could be decomposed into two parts, i.e., the coarse scale solution and the fine scale solution.

An Engineering Comment for Simply Accelerating Seismic Response History Analysis of Mid-Rise Steel-Structure Buildings
TL;DR: In this article , a simple engineering comment is proposed to eliminate the need for initial information about the response in response history analysis of mid-rise steel-structure buildings subjected to ground motion.
Relaxing strong compatibility at atomistic-continuum interface: Introduction to consistent linear coupling method
Pouya Towhidi,Manouchehr Salehi +1 more
TL;DR: This paper explains the notion of coupling models through the interface in the context of continuum mechanics for quasistatic problems and develops a brand new coupling method called consistent linear coupling (CLC), which can be optimized proportional to the computational cost and accuracy.

Unified numerical process modeling of forming and consolidation for thermoplastic composites with prepreg patches
Paris Dilip Mulye,Lionel Morançay,Christophe Binetruy,Sébastien Comas-Cardona,Adrien Leygue,Damien Guillon +5 more
TL;DR: In this paper , the authors present a unified modeling approach that combines a novel pinching shell element, a new elasto-plastic constitutive model for pinching shells in order to provide a unified solution to simulate both forming and consolidation-flow using a shell-based approach.

Topology optimization of multi-material negative Poissons ratio metamaterials using a reconciled level set method
TL;DR: The proposed method simplifies the multi-material topology optimization by evolving each individual material with a single level set function and reconciling the result level set field with the MerrimanBenceOsher (MBO) operator.
