  1. 2015 cdmHUB Workshop

    0.0 out of 5 stars 

    05 Jan 2016 | Series

    Composites Design, Analysis and Manufacturing Workshop held at Purdue University on November 3-5, 2015.  Both lectures slides and lecture videos are presented.

  2. A Unified Theory for Constitutive Modeling of Composites

    0.0 out of 5 stars 

    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...

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

    0.0 out of 5 stars 

    14 Nov 2022 | Online Presentations

    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...

  6. MSC.Patran/Nastran-SwiftComp GUI

    0.0 out of 5 stars 

    01 Apr 2019 | Downloads

    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...

  7. Practical Developments in Multiscale Modeling of Composites

    0.0 out of 5 stars 

    07 Apr 2021 | Online Presentations

    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...

  8. Skill of Using Surface Element in ANSYS

    0.0 out of 5 stars 

    26 Mar 2015 | Downloads

    Dear All, For those ANSYS users, please check the attached skill of using surface element, “Surface_Effect_Elements.pdf”, to apply the surface tangent traction. It works well for homogenization simulations, and also for some beams structure validations. This attached zip file also...

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

    0.0 out of 5 stars 

    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...
