Seismic Evaluation of Welded Moment-resisting Connections
… buildings. Most of the standards specify full penetration butt welds as a suitable type of weld for welding beam flanges to the column flange in seismic areas. New Zealand’s steel design standard is the only standard that allows using fillet welds for the fabrication of welded connections in …

Optimization of superconducting magnetic bearings using finite element modeling
… specific to type II superconductors -such as the partial penetration of magnetic flux- could be used to improve bearing design were considered. Ultimately, a superconducting magnetic bearing with a carrying force of 3210 N was improved to obtain a carrying force of 5200 N.

A prediction of polymer wear using polymer mechanical properties and surface characterization parameters
… surfaces with normal loads which caused full penetration (real and apparent areas equal) and partial penetration (real less than apparent area). Wear data for polyvinylchloride (PVC) and polychlorotrifluoroethylene (PCTFE) was obtained on a pin-on-disk machine using neutron activation analysis …

Accurate Cylindrical-Coordinate Numerical Models For The Analysis Of Hydrologic Tests
… variety of conditions including unconfined flow, partial penetration, layered heterogeneities, and the presence of a homogeneous well skin like existing codes. This program also extends on the capabilities of earlier codes with its ability to simulate a heterogeneous skin where K can vary in both …

MODELING AND TESTING OF WELDED STRUCTURAL JOINTS MACHINED WITH LASER CUTTING TECHNOLOGY
… welded joints (HSS-LCT-W), including full and partial penetration groove welds (CJP/PJP) as well as full and partial strength fillet welds (FSFW/PSFW) specimens, to evaluate capacity, failure mechanisms, and compare performance across aforementioned welding processes. Each specimen consists of …

Optimization of Rib-To-Deck Welds for Steel Orthotropic Bridge Decks
… welds need to be fabricated as one-sided partial penetration welds with minimum penetration of 80% into the rib wall thickness. However considering the thin rib plate thickness, it is very difficult to achieve this penetration without a "melt-through" or "blow-through" defect. Large cost …
