A set of Mater-Bi based biodegradable films was developed and tested, following the selective optimisation of some processing parameters of the film manufacturing along with the optimisation of the structural low-tunnel system design.
The importance of the realistic modelling, which permits the generalization of empirical observations by means of, physically sound, theoretical considerations, is evident, as it allows for the optimisation of the structural design with respect to the site of interest.
The optimisation of the structural modes of the panel is then achieved by placing a number of constraint masses and stiffeners of optimum size and weight at optimum locations on the plate.
Structural analysis of the optimum designs revealed that the active constraint varied greatly between the different designs, and it is therefore recommended that a wider range of loading cases and constraints needs to be accounted for in optimisations that allow the structural geometry to vary compared to those that use a standard geometry.
The results from the structural optimisation study compared the 'generalised Frost Dugdale' law and the traditional Paris law.
In this article, two processes for the structural optimisation are investigated to determine which is most suitable for specific conditions.
Three types of adhesive joint; single lap, double lap and double lap strap, were used for the structural optimisation.
The structural optimisation procedure proposed integrates geometrical modelling, structural analysis and optimization into one complete and automated computer-aided design process.
It is demonstrated that the structural optimisation model presented in this paper is capable of effectively and accurately determining the optimal structural layups of composite blades.
Hence, in order to get robust optimal decisions, the structural optimisation problem with random parameters must be replaced by an appropriate deterministic substitute problem.
