A Unified Theory for Constitutive Modeling of Composites
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...

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...

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

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...
