NCAL: Intermediate Strain Rate Testing

Ongoing
This project seeks to improve servohydraulic testing methods at intermediate strain rates by addressing the well-known problems associated with excessive stress oscillations (ringing) that currently limit our understanding of the mechanical behavior of engineering materials for loading conditions

NCAL: International Documentary Standards Activities

Ongoing
NIST Center for Automotive Lightweighting (NCAL) staff participate in many different international standards committees (e.g. ISO TC 164, ASTM E28 and D30); however, our main focus has been in the mechanical testing of metals and, to a lesser extent, composites. We work on the calibration and

NCAL: Materials Testing 2.0

Ongoing
The traditional approach to calibrating material models, known as Materials Testing 1.0, is a time-consuming and costly process that requires multiple experiments to be performed on different types of testing equipment. This not only results in high capital costs for testing machines but also leads

NCAL: Multiaxial Material Performance

Ongoing
Modern metal forming methods are designed and optimized using digital models of specific manufacturing operations. These models rely on a precise understanding of the mechanical behavior of sheet materials as they undergo multiaxial loading out to large plastic strains without failure (necking or

NCAL: NIST Center for Automotive Lightweighting

Ongoing
The ongoing development of new, advanced lightweight materials presents opportunities for the USA automotive industry to produce better, more reliable and less expensive products provided the new materials can be efficiently manufactured. The use of lightweight materials in automobiles, such as

NCAL: Quantifying Crystallographic Texture and Phase Fraction

Ongoing
Predicting the deformation and force response of a polycrystalline material with the level of accuracy needed by today’s manufacturers requires knowledge of the aggregate deformation and force response of all the grains in the material. Polycrystalline materials will respond differently depending on

NCAL: Tension-Compression Testing

Ongoing
The inability to predict the mechanical behavior of new automotive alloys during forming has generated strong demand in industry for more advanced material models and test methods necessary to calibrate them. Industry is particularly interested in modeling the behavior of advanced sheet metals

NEHRP Extramural Research

Completed
Objective - A task order to assist NIST and the NEHRP agencies in updating the NEHRP Strategic Plan will be awarded to a policy contractor. In addition, other planned FY 2020 extramural research will be assigned by task order to the new IDIQ contractor once that award is made. It is anticipated that

Neighborhood Area Communication Network

Completed
The smart grid is comprised of many networks (domains) with various boundaries that have to be interconnected to provide end-to-end services. The challenge is to design network architectures that can meet the interoperability requirements for inter-domain and intra-domain communications, as

Newtonian constant of gravitation international consortium

Ongoing
The disagreement calls into question our ability to measure small forces on a laboratory scale. It also raises the question of whether the Newtonian force law is a complete description of gravity at these distances. An international consortium is being formed to address this problem. The

Next Generation Fingerprint Technologies

Ongoing
Contactless Fingerprint Capture This project is conducting research in support of emerging non-contact fingerprint acquisition devices. Issues being addressed include: data format standards, best practices, development of methods for certification testing, and assessment of interoperability with

Next Generation Metrics for Cell-Based Therapies and Regenerative Medicines

Ongoing
The science of human health and disease often includes studies of cells, the smallest unit of biological complexity. Microscopic imaging is an important tool in these studies and can provide morphological and molecular information. Molecular microscopic data is most often collected in a static mode

Next Generation Refrigerants for High-Efficiency HVAC&R Equipment
