Multiresolution clustering analysis for efficient modeling of hierarchical material systems
TL;DR: A mechanistic machine learning framework is developed for fast multiscale analysis of material response and structure performance and provides sufficiently high fidelity and speed to reasonably conduct inverse modeling for the challenging tasks mentioned above.
Journal ArticleDOI
An investigation on the coupling of data-driven computing and model-driven computing
TL;DR: In this paper , the authors investigate the coupling of data-driven computing and model-driven (MD) computing for the analyses of engineering structures, and propose a DD-MD solver for the local region of the solution domain where the material constitutive models are difficult to be determined.
Journal ArticleDOI
Stochastic nonlinear analysis of unidirectional fiber composites using image-based microstructural uncertainty quantification
TL;DR: This approach provides insights into the impact of microstructural variabilities, which are shown to have an increasing impact on the nonlinear responses of UD CFRP parts under progressive compression loading and ultimately on the failure rate over time.
Journal ArticleDOI
Micro-mechanics and data-driven based reduced order models for multi-scale analyses of woven composites
TL;DR: In this article, a reduced order model (ROM) is proposed to reduce the order of woven composite materials. But the model is based on the definition of short fibre reinforced matrix material pseudo-grains completed by pure matrix parts.
Journal ArticleDOI
A Meshfree Peridynamic Model for Brittle Fracture in Randomly Heterogeneous Materials
TL;DR: In this article , a peridynamics model for brittle fracture in heterogeneous materials with variability in material microstructures is developed, where the micromechanical parameters are modeled by a finite-dimensional random vector, or a combination of random variables truncating the Karhunen-Lo\`{e}ve decomposition or the principle component analysis (PCA).

The Proper Orthogonal Decomposition in the Analysis of Turbulent Flows
TL;DR: The Navier-Stokes equations are well-known to be a good model for turbulence as discussed by the authors, and the results of well over a century of increasingly sophisticated experiments are available at our disposal.

A theory of the yielding and plastic flow of anisotropic metals
TL;DR: In this article, a theory is suggested which describes the yielding and plastic flow of an anisotropic metal on a macroscopic scale and associated relations are then found between the stress and strain-increment tensors.
Journal ArticleDOI
A self-consistent mechanics of composite materials
TL;DR: In this article, the elastic moduli of two-phase composites are estimated by a method that takes account of the inhomogeneity of stress and strain in a way similar to the Hershey-Kroner theory of crystalline aggregates.
