LEADME ( Laminate Analysis and Design Made Easy ), an educational software useful for the analysis and design of laminated composite structure has been developed. The software encompasses both the micro and macro mechanics analysis of lamina and laminate. The highlight of this software is that, apart from usual laminate analysis, the software is capable to solve practical laminate applications such as analysis of beams and also a design module is included. The software has been developed using MATLAB-Graphical User Interface (GUI) which makes it very user friendly. The results obtained from this software have been validated. It is expected that this software will serve as an educational tool complementing textbooks for students to gain better understanding of composite structural analysis.

<p><strong>Abstract.</strong> Presentation consists of three parts, which are interconnected:</p><ol><li>BIM application for plants treatment and other complicated structures in the field of water management</li><li>Statics of water management structures in the BIM environment</li><li>Application of Common Data Environment (CDE) for water management</li></ol><p>Two areas – statics and water management technology – are crucial for water management structures. Speaking of statics, we mean the statics of reinforced concrete structures. In our company AQUA PROCON s.r.o. we deal with this area comprehensively, ie. from the initial design in the BIM architectural and construction software, through transferring a load-bearing model to BIM software for 3D reinforcement modelling to evaluating model in static design software. All communication is held in Common Data Environment (CDE). Within this environment, a three-way communication is carried out by the designer, contractor and contracting authority. Part of our performance is also above-standard support for reinforced concrete contractors. We provide models of reinforced concrete structures in LOD 400. The use of Common Data Environment (CDE) does not concern only statics, but also the work of all other professions and project participants. Our activities and workflows are based on the philosophy of OPENBIM and IFC.</p>

Structures and control systems of smart laminated composites consisting of graphite-epoxy composites and piezoelectric actuators are designed optimally for the vibration suppression. Placements of piezoelectric actuators, lay-up configurations of laminated composite plates and the H2 control system are employed as design variables and are optimized simultaneously by a simple genetic algorithm (SGA). An objective function is H2 performance with assuming that the state feedback is available. A multidisciplinary design optimization is performed with above three design variables and then the output feedback system is reconstructed with the dynamic compensator based on the linear matrix inequality (LMI) approach. Optimization results show that the optimized smart composite successfully realizes vibration suppression of the system and it is confirmed that the present multidisciplinary design optimization technique is quite efficient to the smart composites.

Abstract Piping is an important material for fluid transportation in modern industry, and well-structured piping can reduce losses due to maintenance and replacement downtime. Therefore it is necessary to design and analyze the pipes in order to optimize their structure. This paper focuses on composite laminated pipes. In this design case, the structural analysis of this pipe will be carried out by applying the laminate theory, and the structural analysis model will be established by using Mathcad software. The stress and strain of each laminate will be calculated by entering the winding angle and the corresponding equations in this software. The final optimal winding Angle can be determined by verifying the winding angles that can be maintained under maximum stress failure criteria using Mathcad contours and detailed tables of winding and torsion angles.
