  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...
