Structural Materials Group

Welcome

STRUCTURAL MATERIALS GROUP (647.02): Provides standard reference materials, calibration and measurement services, and data for predicting structural materials reliability with emphasis on fracture, fatigue, defect detection and life prediction. Develops and standardizes mechanical test methods, and makes non-standard large-scale measurements that match real-world constraint conditions, in environments that represent extreme as well as typical operating conditions. Also develops measurement methods and calibration standards for detection and characterization of materials features that degrade the structural reliability of materials and their joints, including defects, flaws, cracks, corrosion, etc. The group assesses the role of materials in structural reliability as well as life prediction, and conducts failure analyses post-mortem to assist Government agencies, industry, and universities and to increase predictability of structural reliability.

Programs/Projects

Cryogenic Technologies Project—The mission of the Cryogenic Technologies Project at NIST is to conduct research in cryogenics, working with industry and other government agencies in the development of new and/or …

Hydrogen Pipeline Safety—We provide critical data, measurement methods and models that enable safe and economical transport, delivery and storage of hydrogen fuel, an abundant, clean-burning alternative to conventional …

Charpy Verification Program—The objective of the impact verification program is to evaluate the performance of impact test machines used worldwide to qualify structural steels. We offer our customers standard reference …

Bridge Safety—Our goal is to guide improvement in construction codes for both rehabilitated and new structures. Destructive and nondestructive data will allow bridge owners to allocate repair funds to the most …

Microsystems for Harsh Environment Testing—Our goal is to develop and demonstrate a MEMS-based methodology for evaluating time-dependent mechanical properties of materials that undergo exposure to extreme and harsh environments (e.g., …

Pipeline Safety—Our goal is to provide standard test methods and critical data to the pipeline industry to improve safety and reliability. Of particular interest is the testing of high-strength pipeline steels, …

Proficiency Test Results—Proficiency Test (PT) results are available at no cost to customers who have tested SRMs 2092, 2096, and 2098.  A PT result serves as a means to verify the performance of a Charpy impact …
