Abstract The forming limit diagram (FLD) of high-purity niobium sheets used for the manufacturing superconducting radiofrequency (SRF) cavities is presented. Marciniak (in-plane) test was with blanks a thickness 1 mm and blank carriers annealed oxygen-free electronic (OFE) copper. A high formability measured, an approximate true major strain at necking plane 0.44. likely caused by its rate sensitivity 0.112. Plastic anisotropies (r-values) 1.66, 1.00, 2.30 were measured in 0 deg, 45 90 deg...
In this paper, a numerical methodology is presented for the stamping simulation of embossed sheet. A large strains elastoplastic model based on Hill's anisotropic plasticity criteria and coupled with damage identified in case AA1050-O flat sheets. Finally an industrial part simulated validate proposed methodology.
Metastable austenitic stainless steels are prone to strain-induced martensite transformation (SIMT) during deformation at room temperature, as in the case of sheet metal forming processes. The SIMT is influenced by chemical composition, grain size, mode or stress state and strain-rate. In this work, interrupted continuous uniaxial tensile tests were performed AISI 304L evaluate a function strain strain-rate effects. was evaluated feritscope temperature in-situ measurements both XRD optical...
In operation, a Printed Circuit Board (PCB) will face various and repeated thermomechanical loadings that may lead to the failure of copper, thus malfunction PCB itself. order simulate better predict reliability PCBs, constitutive behavior copper has be defined. Therefore, $17 \mu \mathrm{m}$ rolled annealed film frequently used in flexible industry been tested under cyclic tensile-compressive loading. The low elastic limit plastic deformation plays an important role its mechanical behavior....
Two types of cruciform specimens designed for the inverse identification anisotropic yield surfaces sheet metals are presented. A particular emphasis is given on design and sensitivity strain fields to plastic anisotropy. The relations between experimental identified outlined 4 materials with widely different anisotropies.
