PREP0004123 Peridynamic-Based Analysis Researcher

PREP Research Associate

Opportunity No.: PREP0004123

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, and thus requires that such institutions must be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration.

Peridynamic-Based Analysis Researcher

Project Description:

The Materials Measurement Laboratory of the National Institute of Standards and Technology is seeking qualified persons (U.S. Citizens Preferred) to perform a peridynamic-based analysis for failure that can transition seamlessly between brittle and ductile fracture behavior and between quasi-static and dynamic failure. The work will focus primarily on interface failure caused by loading near or away from the interface. The application of this study is relevant to structures of interest in the semiconductor industry, particularly dielectric/metal interfaces subjected to various loading conditions that mimic potential mechanical stresses during fabrication or operational lifetime.

Key Responsibilities: 

• Peridynamic modeling of elastic and elastoplastic behavior from nanoindentation in a brittle substrate with ductile inclusions near the indentation site
• Peridynamic modeling of interface failure due to loading near or distant from the interface between brittle and ductile regions
• Investigation of crack dynamics near material interfaces based on interface strength
• Publish results in peer-reviewed scientific journals and present results at scientific conferences

Desired Qualifications: 

• U.S. Citizens Preferred
• Ph.D. in Materials Science or another related field
• 10 years of experience with computational materials research
• Skilled in using various computational techniques to analyze the elastoplastic behavior of materials, including peridynamic analysis
• Familiarity with materials commonly used in microelectronic devices and assemblies
• Independent worker with strong written and oral communication skills

Other Details:

• Part-time: the participant is expected to work 14 hours a week
• Location: the participant will work at the NIST Gaithersburg Campus.
• Duration: this is expected to be a one-year and four-month position. Extensions are sometimes granted depending on the availability of funds.
• For questions related to the research project or the nature of the work in this position, please contact Dr.Gheorghe Stan (gheorghe.stan@nist.gov). For questions related to the online application or NIST PREP more generally, please contact msu-nistprep@morgan.edu.
