Automated Vehicles and AV Communications

Ongoing
Automated vehicles (AVs), or Automated Driving Systems-equipped (ADS-equipped) vehicles, have great potential to improve our lives by freeing us from the stress of driving and reducing accidents caused by distractions or poor judgement. Connected, reliable, and safe AVs will spark significant

Automotive Lightweighting

Ongoing
The US auto industry spends $600M per year fixing and tweaking forming dies that do not make correct parts. The primary reason that the dies are inaccurate is that the computer models of the dies utilize materials models that are inaccurate. Upon surveying our industrial partners, we determined that

Charpy Machine Verification Program

Ongoing
The Charpy test is a high loading rate test that measures the energy absorbed during fracture, hence providing an indirect measure of impact toughness. For a Charpy machine to maintain an accurate absorbed energy scale, periodic verification with certified specimens is required. To achieve the

Dynamic Plasticity: Non-Equilibrium Mechanics

Ongoing
The optimization of high-speed machining processes through powerful finite element modeling techniques is an important pathway to American manufacturing competitiveness in an increasingly competitive global marketplace. Quantitatively accurate simulations of machining rely on robust constitutive

Fundamentals of Deformation

Ongoing
• We have provided general users from industry, academia and national laboratories with a completely new class of X-ray imaging techniques for materials studies (ultra-small-angle X-ray scattering imaging), that we developed from basic concept to DOE-supported operations at the Advanced Photon
Picture for Hardness and Coating Thickness Standardization and Measurements Project Including Equipment and Standards Organizations

Hardness Standardization and Measurements

Ongoing
DESCRIPTION Purpose: Provide measurement traceability for the Knoop, Rockwell, and Vickers hardness scales and for coating thickness measurements that are based on magnetic methods. Goals: Harmonization of hardness and coating thickness testing protocols, in pursuit of reduction of measurement

Materials Testing in Extreme Environments

Ongoing
Hydrogen is known to have a deleterious effect on steels and other metals, but steels are the most cost-effective and commonly used materials for pipelines and pressure vessels. We are collaborating with the code bodies (ASME B31.12 and ISO 11114-4), DOT, and DOE, to enable the implementation of

Measurement Quality in Hydrogen Storage R&D

Ongoing
The hydrogen storage project targets metrologies that assess kinetics and energetics of hydrogen charging and discharging in combinatorial structures as well as the degradation mechanisms that limit life of use. New capabilities are being developed and several existing measurement capabilities are

NCAL: Diffraction Stress Measurement Under Applied Load

Ongoing
Using X-ray diffraction (XRD) techniques one can measure the full stress tensor just inside the surface of a sheet metal specimen under applied loading. This permits the measurement of biaxial stress states resulting from directly applied deformation (see NCAL: Multiaxial Material Performance) or

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
