A simplified (one step) method called “inverse approach” (IA) for the numerical analysis of the stamping process has been continuously developed by the authors since the end of the eighties. In the present paper we recall the main finite element formulation aspects, for an efficient estimation of the large elastoplastic strains encountered in deep drawing operations. The capabilities of the cod...

Generators for synthetic RDF datasets are very important for testing and benchmarking various semantic data management tasks (e.g. querying, storage, update, compare, integrate). However, the current generators do not support sufficiently (or totally ignore) blank node connectivity issues. Blank nodes are used for various purposes (e.g. for describing complex attributes), and a significant perc...

In the aerospace industry, the production of structural shell components with a prescribed thickness distribution by superplastic forming requires the specification of the initial thickness profile in the undeformed sheet. To this purpose, a finite element simulation methodology developed previously for the analysis of superplastic deformation processes along with the optimum monitoring of the ...

The measurement of immunoglobulin concentrations in serum by a turbidimetric method using a centrifugal analyser (Cobas Bio) is described. In the procedure described it is possible to measure the absorbance of each sample in the buffer reagent in a preliminary run without antiserum (sample blank for correction of colour, turbidity, etc.) In the main run (after adding antiserum) a final measurem...

The concept of shape-manifold is applied here to the optimization of a deep drawn blank considering parameterized tool geometries. By adopting this concept, a realistic post-springback shape of the blank closest to a given ideal target shape is obtained. The global approach is fully automated, from the generation of the tool geometries, to the identification of the optimized design parameters. ...
