• Conventional Versus Additively Manufactured Open-Cell Metal Foams

    Recent work from the MMM Lab reveals some interesting comparisons between conventional open-cell aluminum foam and "twins" created by additive manufacturing, or 3D printing. The work was presented at the Materials Science & Technology conference held here in Salt Lake City.

  • Multiscale Modeling & Materials Characterization

    Multiscale modeling techniques are employed to capture the mechanics acting across multiple length scales. Currently, the group focuses on concurrent multiscale modeling from microstructure to component length scales.

  • Fracture Mechanics

    The group specializes in characterizing and simulating 3-D fracture and fatigue, which play an important role in structural prognosis and materials design and optimization.

  • 3-D Materials Characterization

    Synchrotron-based measurements are used to characterize 3-D crack evolution at the microstructural length scale in polycrystalline metals.

    Measurements are performed at the Advanced Photon Source in collaboration with colleagues from Carnegie Mellon University and Lawrence Livermore National Laboratory.

  • Digital Reconstruction

    3-D measurements are converted to finite element models to perform numerical experiments, or simulations.

  • Concurrent Multiscale Modeling

    Multiscale modeling enables the computation and quantification of fields (like stress) across relevant length scales. Often times, such fields cannot be quantified solely through physical experimentation.

Multiscale Mechanics & Materials Lab

Our group conducts cutting-edge research at the nexus of materials and structures. We couple materials characterization with high-performance computing to address a wide range of research topics that are especially pertinent to the defense, aerospace, and manufacturing communities.

Philosophy


We believe that by pursuing a 3-D understanding of material and mechanical behavior across multiple length scales, we can begin to design smarter, multifunctional, and more sustainable structural systems to suit the needs of a dynamic society.

Tools & Techniques


We employ various types of computing resources to simulate and predict 3-D mechanical behavior of materials, with emphasis on fatigue and fracture. We support numerical modeling with advanced materials characterization techniques, including scanning electron microscopy (SEM), electron backscatter diffraction (EBSD), and high-energy X-ray diffraction microscopy (HEDM) to characterize and quantify material structure at lower length scales. Finally, we develop methods to analyze, visualize, and effectively communicate the 3-D information obtained from our measurements and simulations.
