Adaptive Multi-Scale & Multi-Fidelity Progressive Failure Analysis of Composites

14 Nov 2022

Although high-fidelity modeling of progressive damage has advanced our understanding of failure mechanisms in fibre-reinforced composites, such techniques are currently still too computationally intensive for direct application to composite structures. The multi-scale nature of damage in...

Practical Developments in Multiscale Modeling of Composites

07 Apr 2021

Validated models (be they data driven or physics based) can accelerate the design, certification, and ultimate deployment of novel materials and structures by allowing rapid iteration and virtual experimentation while at the same time minimizing the need for expensive and time consuming physical...

MSC.Patran/Nastran-SwiftComp GUI

01 Apr 2019

A graphical user interface (GUI) has been developed to integrate SwiftComp into MSC.Patran/Nastran for constitutive modeling and providing the automated conversion of the MSG plate and beam stiffness matrix into MSC.Nastran shell and beam element properties and materials. In order to reduce...

Multiscale analysis of multilayer printed circuit board using Mechanics of Structure Genome

23 Jan 2019

The structure of Printed Circuit board (PCB) is very complicated because it consists of woven composites and custom defined conducting layers. To improve the reliability of PCB, it is critical to predict the constitutive relations accurately. This study by implementing Mechanics of Structure...

Woven fabrics UMAT- a coupled material model

02 Aug 2017 | Contributor(s): Ali Roumani

One of the advantages of woven fabrics over unidirectional prepregs is their superior formability thanks to the large shear deformation capability. There exists, however, a limit on the shear deformation of woven fabrics, namely the wrinkling. Applying tension to delay wrinkling during forming...

Abaqus plugins for Nonlinear Acoustics

06 Jul 2017

This paper introduces generalized tools in the form of plugins for a commonly used commercial finite element package Abaqus/Standard to model the nonlinear acoustic methods for detection of delamination damage in composite laminates. The nonlinear acoustic methods typically involve exciting a...

Demystifying Composites Simulation for Performance

25 Nov 2024 | Downloads | Contributor(s): Ali Roumani

The presentation given in IACMI Tutorial session before the 2016 Summer Members Meeting. It tried to explain in layman terms modeling and simulation, and composites, pointed out the barriers we need to overcome to reap full benefits of simulation for composites innovation. 

A Unified Theory for Constitutive Modeling of Composites

14 Aug 2014 | Publications

A unified theory for multiscale constitutive modeling of composites is developed using the concept of structure genomes. Generalized from the concept of the representative volume element, a structure genome is defined as the smallest mathematical building block of a structure. Structure...

Analysis of Slender Structures Using Mechanics of Structure Genome and Open Source Codes

28 May 2014 | Publications

This is the Master thesis from Xin Liu in Prof Yu’s research group. In this thesis, the Mechanics of Structure Genome (MSG) has be used to provide an alternative way to model composite beam-like structures. Basic concept of MSG is introduced as well as the idea of how to carry out...
