Multiscale Homogenization

In this work, a new software for computer-aided design of composite materials with predefined thermomechanical properties is presented in case of incomplete input data. The mathematical basis of underlying computational method of the properties identification is a modified method of multiscale homogenization named reversible multiscale homogenization method. The system has a modular architecture and includes software implementation of the reversible multiscale homogenization method based on a new technique of construction of software implementations of complex computational methods. The latter was named «Graph-based software engineering» (GBSE) and is based on category and graph theories. The corresponding numerical and experimental results were obtained and compared. The expediency of GBSE approach is discussed for the case of the development of complex computational methods required when solving the applied problems of the design of new heterogeneous materials.

Material Information

With the material processing freedoms of additive manufacturing (AM), the ability to characterize and control material microstructures is essential if part designers are to properly design parts. To integrate material information into Computer-aided design (CAD) systems, geometric features of material microstructure must be recognized and represented, which is the focus of this paper. Linear microstructure features, such as fibers or grain boundaries, can be found computationally from microstructure images using surfacelet based methods, which include the Radon or Radon-like transform followed by a wavelet transform. By finding peaks in the transform results, linear features can be recognized and characterized by length, orientation, and position. The challenge is that often a feature will be imprecisely represented in the transformed parameter space. In this paper, we demonstrate surfacelet-based methods to recognize microstructure features in parts fabricated by AM. We will provide an explicit computational method to recognize and to quantify linear geometric features from an image.

Computer-aided design (CAD) has proven effective in enabling novel approaches for tissue engineering applications. This paper demonstrates the applicability of various mathematical methods to design and fabricate bio-mimetic materials via two illustrative examples. Firstly, CAD models of cellular biomaterials that mimic the micro-structure of cuttlefish bone are designed based on the principles of the homogenization method. Secondly, a three-dimensional bi-objective topology optimization approach based upon the inverse homogenization method is used to design scaffold micro-structures with tailored effective stiffness and permeability properties. Consequently, solid free-form fabrication is used to fabricate such cellular bio-mimetic materials, which show a great potential in tissue engineering applications.

Centrifugal pumps are used to transport drinks / fluids with rotational kinetic power conversion to hydro energy dynamics of fluid glide. The rotational electricity is normally derived from the engine or electric motor or turbine. In the simplest case is typical, the liquid enters the pump impeller along or close to the rotating axis and is accelerated through the impeller, flowing radially outward into a diffuser or volute chamber (casing), from in which he came. Contemporary blade impellers in centrifugal pumps used in commercial applications include aluminum or metallic. It is proposed to layout a centrifugal pump, using Computer Aided Design (CAD) software with a variety of metallic alloys and non-metallic composite materials, examine the electricity and deformation using simulation software program. In order to evaluate the effectiveness of Metal Alloys and non-steel composites. The purpose of this observe is to trade the fabric and perform unique analyzes which includes Static, dynamic, evaluation to find the first-rate substances to reduce weight and enhance efficiency the usage of SOLID WORKS software program (Premium Version 2014). It also involves a technique of manufacturing methods to recognise Blower use Non-metal composite fabric.

Synthetic biology is to apply engineering standards to the biology. It has two main aims; first to design and construct biological systems in order to extend the understanding of how they work, and second, to design biological systems for performing valuable tasks like medications synthesis and biofuels production. Due to the complex nature of the biological systems, and similar to the engineering fields, computational methods and computer aided design (CAD) tools, are required to handle this complexity. In this review, existing CADs, languages and data models for synthetic biology are explored. The goal is to provide an insight for the synthetic biologists to take advantage of the available computational tools and to find out the gaps to work on.
