Considerations of some key concepts in fundamental Materials Science

Abstract: For years now Materials Science has been recognized as a specific scientific speciality Does the Science which consists in preparing materials and in studying their properties possess its own basic foundations or, on the contrary, is its fundamental part only constituted by concepts from other scientific fields such as solid state physics, mechanics, electricity, crystallography, etc It is the author's opinion that some particular key concepts such as “processing”, “non-equilibrium and evolution”, for instance, are specific to the Materials Science field and that a better definition of their content and of their mutual action may lead to a “global view” of Materials Science An attempt is made here to look at and define such concepts and to initiate discussion and, above all, controversies

Principles of computer science

Abstract: It is with great pleasure that we welcome you all to COMPSCI 105 SS. This course is conducted during the summer of 2004. This is an intensive course that will be taught in six weeks. It has twelve week duration of lectures when taught during the first and second semesters. As we are covering the same material, it is important that you do your work consistently and not fall behind. This booklet contains the course outline and tutorial questions. While every effort was made to provide accurate information in this course book, it is possible that some small mistakes may not have been corrected, or that some policies need to be changed. Be sure to monitor the course webpage for updates to the course book. We wish to acknowledge Dr. Kevin Novins for providing invaluable advice, lecture notes and other course material from last year's COMPSCI 105 SS. Note: 1. The lectures are to be held in Eng3404. 2. Tutorials are to be held in the GTL (Ground floor Tutorial Lab). 3. Tut1 and Tut2 correspond to Lab and Tut in nDeva. 4. Each tutorial session is two hours with a ten minute break in the middle. 5. Each student should attend 2 different tutorials in accordance to their enrolment every week except in weeks 1 and 4, which are disrupted by Orientation Day and a Public Holiday. Textbook The primary reference for the course is the textbook " Data abstraction and Problem Solving with Java: Walls and Mirrors " by Carrano and Prichard. The exact page numbers in the textbook covered in the course are listed on Page 13 in this course book. You are expected to have easy access to a textbook, and to bring a textbook to all tutorials. We expect most people to buy the textbook, but it may be practical for you to share a copy with a classmate. Lectures Lectures are designed to help you to understand the readings by providing explanations and by giving you a chance to ask questions and to work on simple problems. Outlines for each lecture and related book pages are given on Pages 15 in this course book. You will probably get the most out of a lecture if you try reading the relevant pages before each lecture. However, you could instead use the lectures to prepare you for your reading. Tutorials Tutorials provide a more personal and …

Dynamics of cable structures – Modeling and applications

Abstract: v The objective of the present work is to re-examine and appropriately modify the geometrically exact beam theory, originally developed by Simo, and develop a nonlinear finite-element formulation to describe the static and dynamic behavior of flexible electrical equipment cables. The work is motivated by the need to better understand and predict the highly nonlinear response of flexible electrical conductors to earthquake excitations. Dynamic interaction between flexible cables and interconnected substation equipment is in fact believed to explain some of the severe damage sustained by such equipment in recent earthquakes. In the first part of this report, the nonlinear equations of motion of a beam undergoing large displacements and rotations are derived from the 3D theory of continuum mechanics by use of the virtual power equation. A linear viscoelastic constitutive equation and an additional mass proportional damping mechanism are used to account for energy dissipation. The weak form of the equations of motion is linearized and discretized, in time and space, leading to the definition of a tangent operator and a system of equations solvable by means of an iterative scheme of the Newton type. Particular attention is focused on issues related to how large rotations are handled and how the configuration update process is performed. Numerical examples are presented, and energy balance calculations demonstrate the accuracy of the computed solutions. The beam model developed is then applied to describe the static and dynamic behavior of an electrical conductor tested at the Structural Engineering and Earthquake Simulation Laboratory (SEESL) at the University at Buffalo. Preliminary results of the simulation of free and forced vibration tests are presented. In the second part of the report, an approach is presented for the dynamic analysis of tensegrity structures, a subclass of pin-jointed structures in which the cables can be considered as tensiononly members. Such analyses are characterized by cables in the structure switching between taut and slack states. The approach is based on casting the computation in each time increment as a complementarity problem. Numerical examples are presented to illustrate the approach. Despite the non-smooth nature of cables switching between taut and slack states, the computed solutions exhibit remarkable long-term energy balance. Furthermore, by exploiting some features of the tensegrity model, significant computational efficiency can be gained in the solution of the complementarity problem in each time increment.
