The amount of sensors installed for equipment health monitoring on board engines, aircraft, and vehicles has increased steadily in the digital age. Developing strategies and capabilities to extract useful information from the tremendous amounts of da

The fracture behavior of welded single edge notched tension specimens was examined using constraints and loading conditions which approximated those of a flawed ship structural panel. The specimens were notched and fatigue pre-cracked in the microstr

Mechanical tests were conducted in support of the development of a pulsed gas metal arc welding overlay procedure. Two plates were welded with high and low heat inputs, and subsequent microstructural and mechanical measurements of both the weld metal

Components made from cast nickel aluminum bronze have been used extensively in some seawater systems because of their generally good toughness. However, this alloy can be susceptible to selective phase corrosion. This has led to requirements for remo

Material size effects are predicted for idealized planar micromanufactured structures, as a consequence of the competitive contributions of strain gradient strengthening and loss of microstructural constraints with diminishing dimensions, assuming a

This paper studies dislocation induced internal stresses as introduced in a strain gradient crystal plasticity approach. The need for a second-order crystal plasticity approach is motivated in the context of the analysis of free-standing metal films

A methodology is proposed to evaluate the influence of weld-line surface roughness on the failure of AA5754 tailor-welded blanks (TWBs) loaded in plane-strain tension with major strains oriented along the weld-line. Failure is predicted when a band o

The role of external and internal weld defects during the onset of localization in an aluminum alloy tailor-welded blank (TWB) is presented. Measures of weld surface roughness and weld porosity are acquired and incorporated into a representative fini

Finite element analyses of standard tailor-welded blank (TWB) forming tests were performed to determine the effects of weld modeling techniques on simulation results. Finite element models of TWBs were created that either included a simple representa
