TAILIEUCHUNG - Lifetime-Oriented Structural Design Concepts- P16

Lifetime-Oriented Structural Design Concepts- P16: At the beginning of 1996, the Cooperative Research Center SFB 398 financially supported by the German Science Foundation (DFG) was started at Ruhr-University Bochum (RUB). A scientists group representing the fields of structural engineering, structural mechanics, soil mechanics, material science, and numerical mathematics introduced a research program on “lifetimeoriented design concepts on the basis of damage and deterioration aspects”. | 408 4 Methodological Implementation is obtained. Since the linear system of equations is non-symmetric and looses furthermore the band structure of the generalized tangent matrix it is solved by applying the partitioning technique 91 . Therefore the partial incremental solutions Aur and AuA are calculated in advance. K 1 un 1 Aur n 1r - M iX K 1 i AuA r Afterwards the increments Au Aur AuAAX and AX -f un i x . u- iX j Aur f u un i x i aua A un i x . are computed. Since this procedure is restricted to the corrector iteration a specialized predictor step adopting an user defined step length s is implemented. As shown in Figure the load factor is increased by one and the resulting displacement increment AuA and step length s0 are calculated. Aua K _i u r s0 Aua Aua 1 Afterwards the increments of the displacement vector and the load factor are scaled such that the user defined step length s is obtained. AX -Q 1 Au AuA Selected constraints within the framework of the present generalized arc-length method are summarized in Table . It is worth to mention that the standard control algorithms used in the present book namely the displacement and load controlled analyses are also included in Table and the load controlled Newton-Raphson scheme has already been discussed in Section . As a particular example of the generalized path following method the algorithmic set-up of the arc-length controlled Newton-Raphson scheme is given in Figure . Temporal Discretization Methods Authored by Detlef Kuhl and Sandra Krimpmann The present section is concerned with the numerical methods for the time integration of non-linear multiphysics problems by means of Newmark-a methods as well as discontinuous and continuous Galerkin schemes. Newmark-o time integration methods are using the semidiscrete balance equation evaluated at one selected time instant within a time step and finite Numerical Methods 409 Table . Constraints and .
