In this paper, the bi-directional evolutionary structural optimization (BESO) method is used to find optimal layouts of 3D prestressed concrete beams. Considering the element sensitivity number as the design variable, the mathematical formulation of topology optimization is developed based on the ABAQUS finite element software package. The surface-to-surface contact with a small sliding between...

This paper presents an experimentally validated model for the computational analysis of metal-reinforced wooden composites. The can be used in both research and industry to effectively estimate how much a certain composite design improves bending stiffness strength hybrid component. A based on computer simulations allows prediction mechanical behaviour material consisting several interconnected...

The conventional layout problem is concerned with finding the arrangements of components inside container to optimize objectives under geometrical constraints, i.e., no component overlap and protrusion. In this paper, multi-objective optimization for balance activity requirements functional constraints developed. Integrating accessibility as ensures maintenance or proper operation. However, add...

Desalination with electrodialysis requires cell designs for optimal flow distribution. Such units include polymeric frames, electrodes, membranes and spacers. Frames are used mechanical support of electrodes hydraulic connectors. Their geometry needs to be customized appropriate fluid management compartmentalization. Typically, such frames manufactured by drilling solid plastic blocks. However,...

Abstract This paper present the results of our project to develop preliminary design a jet trainer plane (JTP) with two-person crew, base version which is intended for cadet training. We first consider assumptions and requirements new aircraft, review parameters existing aircraft designs in similarly-purposed class. Next we argue certain choices, regarding layout, cockpit configuration, wing lo...
