Additive Manufacturing Fatigue and Fracture

Ongoing
RESEARCH HIGHLIGHTS FACILITIES and CAPABILITIES PUBLICATIONS - see individual staff webpages on right POST-DOCTORAL OPPORTUNITIES - jump to section below Metal additive manufacturing (AM) is not used in fatigue and fracture critical applications despite industrial need. The goal of this project is

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
