The Enabling Predictive Simulation Research Institute (EPSRI) at Sandia conducts cutting-edge research and development to enable the application of multidiscipline predictive-simulation capabilities. Predictive simulation in this context combines core engineering disciplines with phenomenological understanding and computer modeling and simulation. A wide range of engineering and scientific disciplines is represented, include the following:

  • Thermal, fluid, and aerosciences
  • Structural dynamics, solid mechanics, and material mechanics
  • Electromagnetics and electrical science
  • Materials science

Core activities within the institute encompass a full spectrum of experimental discovery and validation, model development, code development, and engineering analysis in a wide range of scales — from atomic to continuum — corresponding to the requirements of Sandia's national-security mission.

Summer interns at EPSRI conduct research with an emphasis on predictive science and engineering, assisted by a Sandia mentor. Seminars provide opportunities for EPSRI interns to interact with one another and with other Sandia staff. Interns are also given the opportunity to present the results of their research to the Sandia scientific community.

In previous summers, EPSRI participants have been students from Brown University; Cornell University; the Georgia Institute of Technology; North Carolina State University; Stanford University; the University of Colorado at Boulder; and several universities within the University of California system, including the Berkeley, Davis, and Los Angeles campuses.

At the end of their internships, these students presented papers on the following topics:

  • Variable-element topology finite-element methods
  • Continuum mechanics
  • Crystal plasticity
  • Computational atomistic simulations
  • Continuum-damage mechanics
