The single point incremental forming (SPIF) is one of the dieless forming processes which is widely used in the sheet metal forming. The correct selection of the SPIF parameters influences the formability and quality of the product. In the present study, the Gurson-Tvergaard Needleman (GTN) damage model was used for the fracture prediction in the numerical simulation of the SPIF process of alum...

The press formability of a dual-phase stainless steel sheet consisting of ferrite and austenite phases was estimated from a viewpoint of texture using plastic strain ratios (r-values). From the comparison of the mechanically obtained r-values by tensile test and the r-values calculated from the crystal orientation distribution functions (ODFs) of each phase, we found the ferrite phase contribut...

Point-of-care testing is a rapidly evolving yet complex field. As your POCT program grows, take the time to understand the regulations, as they are important to ensuring patient safety. The regualtions established CLIA are designed to ensure consistent and reliable laboratory results that can accurately impact patient care. When beginning your look into POCY, first identify what labs can direct...
