โœฆ Synopsis

Efficient modelling of many problems in the finite-element analysis of structural and other continuum problems requires substantial simplification of the design geometry. Tools are needed for the efficient transformation of the detailed design geometry into an appropriate analysis model. It is argued that the medial axis and surface transform of geometric models provide an alternative representation that has many attractive properties for analysis feature recognition and simplification. Strategies for identifying possible idealizations, controlling their application, and estimating the associated errors appear feasible. Some requirements for geometric-modelling tools are identified.

In this paper, the determination is considered of the required experimental accuracy that must be attained when updating finite element models with use of measured vibration test data. A theoretical basis is developed for FRF-based updating techniques, as these use measured data directly. It is show
