this paper investigates the earing phenomenon in deep drawing of aa3105 aluminum alloy, experimentally and numerically. earing defect is mainly attributed to the plastic anisotropy of sheet metal. in order to control such defect, predicting the evolution of ears in sheet metal forming analyses becomes indispensable. in this regard, the present study implements the advanced yield criterion bbc20...

Warm deep drawing of polypropylene, a semi-crystalline thermoplastic polymer, is studied using finite element analysis. In this process, circular polypropylene blank preheated to temperature much below its melting and drawn into the shape flat-bottom cylindrical cup punch-die combination, both initially at 25°C. The material model used for analysis considers effects varying strain rate during p...

By leveraging recent progress of stochastic gradient descent methods, several works have shown that graphs could be efficiently laid out through the optimization a tailored objective function. In meantime, Deep Learning (DL) techniques achieved great performances in many applications. We demonstrate it is possible to use DL learn graph-to-layout sequence operations thanks graph-related this pap...
