The mechanical characterization of advanced pore morphology (APM) foam, consisting of sphere-like metallic foam elements, is very limited since APM foam has been developed only recently. The purpose of this research was thus to determine the behavior of APM spheres and its composites when subjected to compressive loading. Single metallic APM spheres have been characterized with experimental testing and computational simulations, providing the basic properties and knowledge for an efficient composition of composite APM foam structures. Then, the APM foam elements were molded with epoxy matrix resulting in new composite structures. These composites have been adhered together with the epoxy resin achieving partial and syntactic morphology. The mechanical characterization of composite APM foam structures was based on experimental testing results with free and confined boundaries. The results of the performed research have shown valuable mechanical properties of the composite APM foam structures. Furthermore, they offer new possibilities for their use in general engineering applications.

The paper discusses a framework for intelligent decision support for structural design analysis using a finite element method. The intelligent environment presented is composed of several knowledge-based modules in order to address some major bottlenecks within the analysis-based design improvement process. The prototypes of four intelligent modules are presented within this context. These are: an intelligent module for supporting some initial decisions within the design analysis process, an intelligent module for finite elements’ selection, an intelligent module for finite element mesh design, and an intelligent module for supporting the results’ interpretation process. According to the feedbacks of those experts who participated in the evaluation process, these prototypes could be applied as useful supporting tools for inexperienced designers in design practice, as shown in certain examples presented in the paper.

This paper deals with the manipulability problem of a novel 3 DOF MR compatible haptic mechanism, considering limited space and its visualisation. An appropriate 3D visualisation method has been developed for analysing the manipulability characteristics of a haptic mechanism within an MR environment.
