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...

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...

VABS: Modeling Composite Beam-like Structures with 3D FEA Fidelity

0.0 out of 5 stars

06 Feb 2021 | Contributor(s): Nikki Huang

This presentation was given at Altair Virtual ATCx Composites: https://atcxcomposites.virtual.altair.com/. Variational asymptotic beam section (VABS) is a unique technology continuously funded by the US Army since 1988 and it has become a tool of choice in the helicopter and wind turbine...

iVABS

19 Nov 2020 | Contributor(s): Nikki Huang

iVABS (namely integrated VABS), is a design framework for composite slender structures (also called composite beams) such as helicopter rotor blades, wind turbine blades, high aspect ratio wings, bridges, shafts, etc. This framework bundles PreVABS, VABS, GEBT, Dakota, along with msgpi for...

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...
