  • 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.

  • 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.

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 and data-driven analysis (including machine learning) 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

The MMM Lab employs 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.
