Model-Based Manufacturing Services

Ongoing
Manufacturing systems need to transform towards a new service-oriented architecture to benefit from new smart manufacturing technologies such as IIoT, AI, and Big Data Analytics. A service-oriented manufacturing system (SOMS) is a dynamic composition of networked manufacturing software and cyber

Modeling Methodology for Smart Manufacturing

Ongoing
Objective: Develop new modeling methodologies, guidelines, and software tools to enable manufacturers to more easily apply analytical methods to manufacturing operations and processes. Technical Idea: Manufacturers would realize great benefit were the costs of composing analytical models reduced

Monitoring, Diagnostics and Prognostics for Manufacturing Operations

Completed
Objective - Develop and deploy measurement science to promote the implementation, verification, and validation of advanced monitoring, diagnostic, and prognostic technologies to minimize unplanned downtime and optimize planned downtime in manufacturing operations. What is the technical idea

Multifunctional 3D Printable Polymer-Metal Composites

Ongoing
Recent advances in additive manufacturing (AM) have positioned metals and polymers as two key materials. Typically, AM of these two materials involves incompatible methods and conditions. The novel multifunctional polymer-metal composites in this project incorporate low-melting alloys with

Nanocalorimetry for Semiconductors and Semiconductor Process Metrology

Ongoing
In September 2022, NIST published a report titled Strategic Opportunities for U.S. Semiconductor Manufacturing , which cited, among other challenges, the need to understand and improve heat dissipation and performance in advanced microelectronics. Specifically, there needs to be better measurements

NCAL: Data Management

Ongoing
In the mechanical testing and materials science communities there is not a widely accepted solution for data management of test data. As part of NIST efforts on data archiving, provenance, and availability, we have worked to improve our data practices. We have extended our system beyond many out-of

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

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

NIST Automated Vehicles Program
