Plenary Lecture 1

Cost Estimating Methods of Industrial Products

Professor Gheorghe Oancea Manufacturing Engineering Department

Transilvania University of Brasov Romania

E-mail: [email protected] Abstract: It is well known that the competitiveness of industrial products is mostly based on cost, quality and innovation. The worldwide competition has demonstrated that it is not important how good the project is, if the product couldn't be designed and manufactured in a short time, with competitive cost and adequate quality. Therefore, the design must be made not only according to the requirements and technical specifications of the product, but also using innovative manufacturing processes with a maximum economic efficiency. The production cost is the factor with major influence on the market and its decrease is the key for companies to survive overall in the world. The lecture presents the cost estimation methods and a software tool used for manufacturing time calculation and cost evaluation for industrial products with high level of customization manufactured by chip removing processes and cold forming processes. Brief Biography of the Speaker: Gheorghe Oancea was born in Romania on 11th April 1966. His university education was finished with a diploma degree in Manufacturing Engineering at Transilvania University of Brasov, Romania in 1990. He obtained the PhD degree in Manufacturing Engineering field at the same university in 1997, and he became PhD advisor in 2009. Since 2003, he is full professor at Manufacturing Engineering Department, Transilvania University of Brasov. He is currently involved in undergraduate and postgraduate teaching in the area of CAD/CAPP/CAM Systems. Professor Gheorghe Oancea has authored and co-authored of 12 books and more than 100 scientific publications. He actively participates in numerous conferences with papers as well as chairman, co-chairman and member of the International Scientific Committee. He also is reviewer for conferences and journals.

Plenary Lecture 4

Modeling of Vibrations of Lumped and Continual Mechanical Systems by Ordinary Differential Equations

Professor Jan Awrejcewicz Technical University of Lodz

Department of Automation and Biomechanics Lodz, Poland

E-mail: [email protected] Abstract: Example taken from mechanical engineering, i.e. dynamics of a triple physical pendulum exhibiting a plane motion (lumped system) and dynamics of a cylindrical shell with the circular cross section (continual system ) are studied. In the first case the Lagrange’a equations are used to derive the governing second order ODEs, whereas in the second case strongly nonlinear PDEs are reduced to a truncated set of ODEs via FDM (Finite Difference Method) and the higher order Bubnov-Galerkin approximations. Mathematical modeling of triple pendulum includes details, taking into account some characteristic features (for example, real characteristics of joints built by the use of roller bearings) as well as some imperfections (asymmetry of the forcing) of the real system. Parameters of the model are obtained by a combination of the estimation from experimental data and direct measurements of the system's geometric and physical parameters. A few versions of the model of resistance in the joints are tested in the identification process. Good agreement between both numerical simulation results and experimental measurements have been obtained and presented. Some novel features of our real system chaotic dynamics have been reported. In the case of the circular cylindrical shell dynamics the problems related to its regular, bifurcational and chaotic dynamics are illustrated and discussed, as well as it’s local (global) stability loss versus control parameters. In addition, the convergence and validity of the applied numerical algorithms are studied. The lecture includes movies and animations of regular and chaotic dynamics of the analysed systems.

Abstract: Bearing capacity and settlement behavior are two key properties required in the design of foundations. In conventional geotechnical engineering practice, the bearing capacity of saturated soils are typically analyzed using two different approaches; effective and total stress approach using Terzaghi (1943) and Skempton (1948) bearing capacity theory, respectively. In most cases, the bearing capacity of unsaturated soils is also interpreted using the effective stress approach regardless of the type of soil (i.e., coarse- and fine-grained soils), which is not rational. In addition, the conventional theory for the estimation of immediate settlement using the modulus of elasticity, E of saturated soils cannot be extended for unsaturated soils or compacted soils as they do not attain saturated condition during their service period. The mechanics of saturated soils are however employed in practice due to the following two reasons: (i) extending the approach used for saturated soils to soils that are in a state of unsaturated condition provides conservative analysis and (ii) there is no simple framework to design geotechnical structures using the mechanics of unsaturated soils. In this paper, simple models are proposed for predicting both the bearing capacity and the modulus of elasticity of unsaturated soils for different types of soils. These models use the Soil-Water Characteristic Curve (i.e. SWCC), which is defined as the relationship between the water content and soil suction, as a tool along with saturated soil properties (i.e., bearing capacity and modulus of elasticity under saturated condition). Details of how the proposed models can be implemented into geotechnical engineering practice and differences associated with the proposed methods and conventional methods are also discussed with practical examples. Lastly, a method to estimate matric suction of as-compacted soils using a pocket penetrometer is described. The simple techniques proposed in this paper should encourage the geotechnical engineers to implement the mechanics of unsaturated soils in practice.
