Automotive Lightweighting

Ongoing
Our objective is to support the efforts of the US automotive industry and its suppliers to incorporate advanced lightweight materials for improving fuel economy

Fundamentals of Deformation

Ongoing
This project provides new measurement methods, property data and simulations for areas critical to US manufacturing, describing the mechanisms responsible for

High Rate Testing

Ongoing
This project involves sample geometry and metrological development for high rate servohydraulic testing. (Content to be uploaded soon)

Marciniak Multiaxial Testing

Ongoing
A novel method for measuring multiaxial stress-strain curves in sheet metal has been designed based on a modified Marciniak punch stretching geometry. Since the

Physical Infrastructure: Connections

Completed
Using a complementary approach of experimental measurements and detailed finite element analysis, we will develop more realistic yet computationally efficient

Springback

Elastic springback compensation is a long-standing issue for formed sheet automotive components. The ability to predict the magnitude of springback as a

Tension-Compression Testing

Ongoing
Project goal is to develop a fully-instrumented version of the tension-compression test, to enable measurement of the Bauschinger Effect in sheet metal, and to

Uniaxial Tension Beyond Necking

Ongoing
This project is developing methods to extract valid tensile stress-strain data out of an ASTM E8-type test beyond the point of necking.

X-ray Stress Measurement

Ongoing
Using X-ray diffraction techniques one can measure the full stress tensor just inside the surface of a sheet metal specimen under applied load. For experiments

Yield Surface Measurement

Ongoing
In order to calculate the stresses that develop within a formed part, and thereby compensate for such things as elastic springback, it is necessary for the
