Mechanical Properties and Mechanics

Mechanical Properties and Mechanics

The Mechanical Properties and Mechanics Group (MP&M) conducts applied research and development activities to support the missions of the U.S. Department of Energy to increase the availability of clean, abundant energy; restore and protect the environment; and contribute to national security.

Publications

High burn-up spent nuclear fuel transport reliability investigation

Transportation packages for spent nuclear fuel (SNF) must meet safety requirements under normal and accident conditions as specified by federal regulations. During road or rail transportation, SNF...

Damage-tolerant metallic composites via melt infiltration of additively manufactured preforms

A356/316L interpenetrating phase composites were fabricated by infiltrating additively manufactured 316L lattices with molten A356. Measurements of the thermal conductivity of the composites showed...

Evaluation of Fuel-Borne Sodium Effects on a DOC-DPF-SCR Heavy-Duty Engine Emission Control System: Simulation of Full-Useful Life

For renewable fuels to displace petroleum, they must be compatible with emissions control devices. Pure biodiesel contains up to 5 ppm Na + K and 5 ppm Ca + Mg metals, which have the potential to...

Research

MP&M specializes in the mechanical evaluation and characterization of structural and functional materials; in experimental mechanics and the development of test methods, design codes and life-prediction analyses; in establishing relations among processing, microstructure and mechanical properties of materials and structures and how these change as a function of time, stress, temperature and environment.

MP&M manages a large collection of unique mechanical testing equipment with capabilities to conduct uni- and multi-axial tests from cryogenic to very high temperatures in air or controlled environments. Many of these facilities are available to researchers in industry and academia through the High Temperature Materials Laboratory User Program, through Cooperative Research and Development Agreements (CRADAs) and Work-for-Others contracts.

MP&M staff members have expertise with a wide range of materials including metals, ceramics, polymers and glasses, metal, polymer and ceramic matrix composites, concrete, and functional materials (magnetic, electronic). MP&M also has capabilities for finite-element stress analyses and probabilistic analyses of materials and structures.
