WebAdditionally, domain decomposition can sometimes reduce the computational complexity of the underlying solution method. ... ‘Iterative substructuring methods for p-version finite … Five domains that are well suited for substructuring are: Physical domain Modal domain Frequency domain Time domain State-space domain The physical domain concerns methods that are based on (linearised) mass, damping and stiffness matrices, typically obtained from numerical FEM modelling. See more Dynamic Substructuring (DS) is an engineering tool used to model and analyse the dynamics of mechanical systems by means of its components or substructures. Using the dynamic substructuring … See more To establish substructuring coupling / decoupling in each of the above-mentioned domains, two conditions should be met: • Coordinate compatibility, i.e. the connecting nodes of two substructures should have equal … See more In order to write out the equations for frequency based substructuring (FBS), the dynamic equilibrium first has to be put in the frequency … See more The roots of dynamic substructuring can be found in the field of domain decomposition. In 1890 the mathematician Hermann Schwarz came up with an iterative … See more Dynamic substructuring can best be seen as a domain-independent toolset for assembly of component models, rather than a modelling … See more The physical domain is the domain that has the most straightforward physical interpretation. For each discrete linearised dynamic system one is able to write an equilibrium between the externally applied forces and the internal forces originating from intrinsic inertia, … See more • Vibration • Finite element method • Finite element tearing and interconnect (FETI) • Mechanical engineering • Acoustic engineering See more WebSubstructuring methods are enabling efficient re-analysis for applications like model updating and optimization, but also to vary joint properties for nonlinear analysis and … eberspacher plug passt china wabasto
