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...

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...

Skill of Using Surface Element in ANSYS

14 Feb 2014 | 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...

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

14 Aug 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...
