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...

Injection Overmolding Manufacturing Process Simulation

29 Jun 2017 | Online Presentations

Injection over-molding or hybrid molding is a high-rate composites manufacturing process for fabrication of structural components with complex geometries.  The structural backbone is provided by a continuous-fiber woven prepreg while the geometric complexity is realized via injection...

A Unified Theory for Constitutive Modeling of Composites

18 Apr 2016 | 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

18 Apr 2016 | 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...

HyperSizer for Composites: Insanely Fast Laminate Optimization

31 Mar 2015 | Tool Information

95% of users, without user manual, and without instruction, will be able to import their FEM and produce optimum composites laminates that satisfy all analyses to all load cases within the first 10 minutes. Your automatically updated model will have minimum weight and fully producible laminates...

Structure Genome: Fill the Gap between Materials Genome and Structural Analysis

29 Nov 2014 | Publications

A new concept, Structure Genome (SG), is proposed to fill the gap between materials genome and structural analysis. SG acts as the basic building block of the structure connecting materials to structures and the mechanics of SG governs the necessary information to link materials genome and...
