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

    0.0 out of 5 stars 

    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

    0.0 out of 5 stars 

    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. Constitutive modeling for time- and temperature-dependent behavior of composites

    0.0 out of 5 stars 

    08 Jan 2020

    Structural integrity, durability, and thermal stability represent critical areas for adequately modeling the behavior of composite materials. Polymeric matrices are prone to have time-dependent behavior very sensitive to changes in temperature that influence the effective properties of the...

  4. MSC.Patran/Nastran-SwiftComp GUI

    0.0 out of 5 stars 

    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...

    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...

  6. VABS: Powering Simple Beam Elements with Detailed 3D FEA Fidelity

    0.0 out of 5 stars 

    06 Jan 2017

    This presentation gives a brief introduction to VABS, a general-purpose cross-sectional analysis, which can power conventional, simple beam elements with detailed 3D FEA fidelity. 

  7. A Unified Theory for Constitutive Modeling of Composites

    0.0 out of 5 stars 

    18 Apr 2016

    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...

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

    0.0 out of 5 stars 

    29 Nov 2014

    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...
