New Routes to Advanced Simulation of Material Forming
We developed in recent years a novel technique,called Proper Generalized Decomposition (PGD),based on the assumption of a separated form of the unknown field.It has demonstrated its capabilities in dealing with highdimensional problems overcoming the strong limitations of classical approaches.Many challenging problems can be efficiently cast into a multidimensional framework.For instance,parameters in a model (loads,initial conditions,boundary conditions,material parameters,geometrical parameters,...) can be set as additional extra-coordinates of the model.In a PGD framework,the resulting model is solved once for life,in order to obtain a general solution that includes all the solutions for every possible value of the parameters,that is,a sort virtual chart.Under this rationale,optimization of complex problems,uncertainty quantification,simulation-based control and real-time simulation are now at hand,in highly complex scenarios and on deployed platforms.
