Nonintrusive reduced order model for parametric solutions of inertia relief problems

The Inertia Relief (IR) technique is widely used by industry and produces equilibrated loads allowing to analyze unconstrained systems without resorting the more expensive full dynamic analysis. main goal of this work develop a computational framework for solution parametric structural problems with IR Proper Generalized Decomposition (PGD) method. First, method formulated in setting both material geometric parameters. A reduced order model using encapsulated PGD suite then developed solve problem, circumventing so-called curse dimensionality. With just one offline computation, proposed PGD-IR scheme provides vademecum that contains all possible solutions predefined range approach nonintrusive it therefore be integrated commercial finite element (FE) packages. applicability potential shown three-dimensional test case complex industrial case. first example highlight numerical properties scheme, whereas second demonstrates shows possibility integrate within FE package. In addition, last use generalized multi-objective optimization setting.
