摘要:

AbstractThis special event held at the 1996 Annual Meeting of the GVC addressed the bright and the dark sides of technological forecasting. The review article on pp. 44 to 54 presents the content of a lecture delivered by Prof. Dr. ORTWIN RENN, Baden‐Württemberg Academy for Assessment of the Consequences of Technology. As an introduction to the assessment of the consequences of technology, Prof. Dr.‐Ing. KARL STEPHAN, University of Stuttgart, examined the significance of the assessment of the consequences of technology for the professional activities of the engineer. In this issue we publish extracts from his lec

摘要:

AbstractPeople depend upon technology, at work and in everyday life. Without organisational and technological intervention in nature humankind would never have been able to maintain the population densities encountered today or uphold an ethical claim to an individual livelihood in dignity. At the same time, however, technology creates new risks. The extent to which the risks arising are balanced by the desired benefits often evades prediction since many consequences of the application of technology are uncertain and are also judged ambivalently by the persons affected. Forecasts can only predict probable or possible developments, but cannot overcome the genuine uncertainty surrounding the future. For this reason assessment of the consequences of technology cannot reveal all negative effects, or even promise the certainty of a positive cost‐benefit balance. Instead, it is the task of assessment of the consequences of technology to initially establish the potential positive and negative consequences according to the best available knowledge and on the basis thereof to harmonize the possibilities of modifications and conditions of introduction with the developers and users of technology. The most suitable approach utilizes discursive procedures in which scientists, manufactures, users, and other affected persons together have to assess the possible consequence

摘要:

AbstractThe use of ceramic materials in chemical engineering is on the increase. They have a number of advantageous properties which prove technically and economically beneficial. Realization of these benefits requires cooperation between component manufacturers and users, with due attention to appropriate design. Example of successful use are discussed.

摘要:

AbstractThis contribution is concerned with computer support in the planning and execution of production with regard to the chemical industry. It examines the question whether strategies and software from production engineering can also be used in the processing industry and the extent to which chemically specific supplementation is necessary.

摘要:

AbstractThe importance of the detailed analytical proof of fatigue strength of pressure vessel components is steadily growing in order to ensure safe long term operation of chemical plant and power stations. The state of the art is represented by the notch stress oriented concept of the proof of fatigue strength. It is implemented according to increasing quality requirements within pressure vessel codes and guidelines for analysis such as the German AD‐Merkblatt S 2. The main problem of its practical application is the stress analysis for fatigue including fatigue crack initiating notch stresses. Currently, only numerical instruments of analysis such as the finite elements method (FEM) allow for detailed modelling and analysis according to these needs. General results for standard pressure vessel components such as vessel‐to‐nozzle connections can be derived from parametric studies based on the finite elements method in case of swelling cyclic loading (start‐up and shutdown procedures). These results can be further processed within computer programs enabling the engineer as a user to carry out the detailed proof of fatigue strength for minimum expe
