T1 - Determination of the Temperature of Dissipative Warming and Parameters of Fracture in Elastomers with using of Singular Finite Elements N2 - For modeling of singular fields of stresses and deformations in elasters with a crack is offered to use of three-dimesional a special finite element. Weak compessible of elasters is taken into account on the basis of threefold approximation of fields of displacements, deformations and function of volume change. At intensive cyclic loading of the elastomer constructions with a crack it is necessary to take into account warming and large deformations at the crack top. The stress-deformed state elasters with a crack is determined from the decision of a nonlinear problem by a modified method Newton-Kantorovich. Account stress intensity factors for a rectangular plate with a various arrangement of a through crack is executed. Process of development of a surface crack and dissipative warming in prismatic a element of shift is investigated.

T1 - Optimized Models of Modes Choice for Displacement of technical Systems Objects N2 - The effectiveness of working processes accomplished by various technological machines to a large extend depends on working quality of supply, transporting and orientating mechanisms which are very often produced as positional hydro-mechanical systems. The choice of their best type and regimes of work requires construction and analysis of models of their optimum steering which are complicated by nonlinearness, multy-criterialness of problem and also by occasional outbreaks of parameters and moments of steering regime changing. It was developed the common structure of such systems allowing within common scheme to vary the complexity degree of PHMS and the methods of inhibitory efforts supplement. For some systems which are complicated in series (from two-measured linear system to nine-measured non-linear) puzzles of the most fast zero-ambit getting are solved and two-criterial problems are analyzed. (T-min-speed, Z(T)- accuracy). There are suggested the computing procedures of optimum PHMS synthesis. The effectiveness of accepted methods of solving is asserted by the analogy of the results of gradually complicated models investigation and by their good analogy with the natural experiment. It was exposed the sense of heuristic methods of improving of approximately optimum steering, their elaboration on the base of theoretical models. The basic methods of optimum PGMS construction were also nominated.

T1 - Digital Architectural Photogrammetry for Building Registration N2 - For many purposes geometric information about existing buildings is necessary, e.g. planing of conservation or reconstruction. Architectural photogrammetry is a technique to acquire 3D geometric data of buildings for a CAD model from images. In this paper the state of the art in architectural photogrammetry and some developments towards automation are described. The photogrammetric process consists of image acquisition, orientation and restitution. Special attention is put on digital methods, from digital image acquisition to restitution methods, supported by digital image processing. There are a few field of development towards automation, e.g. feature extraction, extraction of edges and lines and the detection of corresponding points. The acquired data may be used in a CAD environment or for visualization in Virtual Reality Models, using digital orthoimages for texture mapping.

A1 - Eshete, T. T1 - Grundlagen zur Methodik der Verschneidung stahlbautypischer Körper in einem CAD-System N2 - Der Effekt des praktischen Einsatzes von CAD-Systemen im Stahlbau erschöpft sich heute weitgehend in einer Verbesserung der Qualität der Planungsunterlagen und in der Verkürzung der Bearbeitungszeiten. Dabei ist bei schwierigen individuellen Konstruktionen die Einsparung an Arbeitszeit oft nicht sehr markant gegenüber einer traditionellen Arbeitsweise. Die dreidimensionale Erfassung, Speicherung und Verarbeitung von Konstruktionsdaten im Rechner verlangt neben größeren Rechenleistungen neue Verfahren für die Behandlung dieser Daten. Die Möglichkeiten der Automatisierung stahlbautypischer Produktionsvorgänge und einer variablen, computergestützten Planung erfordern wissenschaftlich-technische Betrachtungen des Gesamtproblems. Ausgehend von den Anforderungen des Stahlbaus wird ein neues dreidimensionales Volumenmodell für den rechnergestützten Entwurf und die Konstruktion erarbeitet. Es werden grundlegende Methoden zur Problembehandlung aufgezeigt. Die Methodik basiert im wesentlichen auf der Methode der Inzidenz-Matrizen, um die Beziehungen zwischen topologischen und geometrischen Informationen eines Körpers darzustellen. Die Ermittlung der lokalen Mannigfaltigkeiten wird mit dem Euler-Polyedersatz verglichen und an Beispielen demonstriert. Eine neue Methode zur Ermittlung der lokalen Mannigfaltigkeiten wird dargestellt. Stahlbauspezifische Konstruktionen werden erzeugt und ihre Gestalt nach Anforderungen verändert. Im besonderen werden stahlbauspezifische Ausklinkungen und Verschneidungen erarbeitet und an Beispielen präsentiert.

A1 - Röder, J. T1 - Object oriented databases in software development for structural analysis N2 - A technique for using object-oriented technologies to write structural analysis software has been developed. The structural design information of an individual building is stored in an object-oriented database. A global database provides general design values as material data and safety factors. A class library for load elements has been evolved to model the transfer of loads in a building. This class library is the basis for the development of further classes for other structural elements such as beams, columns or slabs. A software has been developed to monitor the forces transferred from one structural member to another in a building for load cases and combinations according to Eurocode 1. The results of the analysis are stored in the projects database from which a structural design report may be generated. The software was developed under Microsoft Visual C++. The Microsoft Foundation Class Library (MFC) was used to program the Graphical User Interface (GUI). Object Linking and Embedding (OLE) technology is useful to include any type of OLE server objects for example texts written with a word processor or CAD drawings in the structural design report. The Object-Oriented Database Management System (OODBMS) ObjectStore provides services to store the large amount of objects.
