Interests

My research expertise lies at the confluence of materials science, solid mechanics, and manufacturing. The specific areas include the following:

a. Building integrated models that focus on the process-structure-performance relationship in advanced materials and alloys, of specific interest is prevention of failure due to processing defects and heterogeneous deformation;
b. Quantifying the local energy barriers to deformation from defects within the material using atomistic simulations, including density functional theory and molecular dynamics, which is the foundation for modeling without the need for fitting constants; and
c. Microstructure based characterization of materials and validation of model through strain measurements from digital image correlation, stress measurements from synchrotron based in-situ x-ray diffraction, and description of the defects within the materials from transmission electron microscopy and electron backscattering diffraction.

In addition to the above areas, my current research interests also include microstructure-based process/manufacturing modeling, multi-physics modeling, multi-scale modeling, thermo-mechanical processing/deformation, microstructure evolution, fatigue, fracture, creep, and design of materials.

Research Areas

Professor Sangid’s research activities combine knowledge of materials science, solid mechanics, and advanced manufacturing to solve complex problems in materials behavior and processing. His research group employs physics-based computational modeling and design tools, which are experimentally validated and verified. The goal of this work is to improve our understanding and our tools for designing, processing, and lifing materials through simulation-based modeling of the microstructural defects. His research specifically focuses on (micro)structure to performance modeling, via the use of atomistic simulations to inform multi-scale models for plasticity, fatigue, and fracture of metallic alloys and high temperature composites. Both material systems have direct applications in Aerospace Engineering. Many times, it is necessary to start at the atomistic level to gain a quantifiable understanding of the deformation pathways and failure mechanisms at component scales. Further, there is also an experimental component to his research as he does advanced materials testing and characterization including digital image correlation, advanced microscopy, and high-energy x-ray diffraction. Thus, the most advanced characterization and interrogation methods are exercised at each scale to verify and validate model predictions, including four dimensional mapping of ‘defect’ features, strain fields, and complex stress states within the material.

Professor Sangid is the principal director of the Advanced Computational Materials and Experimental Evaluation (ACME) Laboratory. The ACME group’s philosophy is to simultaneously address fundamental research needs and implement this knowledge into integrated models that can directly aid in and transform our design methodologies providing pragmatic engineering solutions. The overarching goal and uniqueness of the ACME group’s modeling strategy is to avoid fitting parameters prevalent in classical engineering models, while providing a general framework, which allows: (1) Easy integration and modification of software, (2) Uncertainty quantification and probabilistic lifing, and (3) Pragmatic tools to answer production questions.
