Object-oriented approach to interactive analysis of structures
The paper presents a novel, object oriented (OO) approach to structural modeling and analysis to enable interactive, virtual prototyping in the next generation of the design environment. The interactivity of analysis of build-up structures can only be achieved by reusing results of component analyses, therefore, the applicability of data based analysis to the OO approach is investigated. An object in the OO approach is a neurocomputing model of a structural component developed for a given set of parameterized design variables, loading, and 'smart' connectors. Such connectors define how the given component is connected to the assembly, and what is the validity of such a connection. Since component models can be subject to affine transformations, a family of similar structural components is available for modeling. Neurocomputing models are used to enable data based analysis, because they can relate any design variables and load conditions to the selected system response. The applicability of feedforward and feature-sensitive neural nets is examined in this context. Object oriented modeling is illustrated with a design of an assembly of beams using a single-point (SP) connector and an assembly of plates subject to a thermal load using a multi-point (MP) connector.
