Weiterentwicklung von Berechnungsverfahren zur Beurteilung der Betriebsfestigkeit unter besonderer B
FKM 1994
Booklet No. 186
Project No. 134
Abstract:
In the project 'Computer-aided fatigue strength assessment' of the Forschungskuratorium Maschinenbau, a computer program was developed to support experts who assess fatigue strength. The program is intended to help speed up the development of new products by using numerical methods for fatigue strength analysis and to facilitate the computational fatigue strength verification for large components and small series. The material and component information system, which is part of the developed program, should contribute to the accumulation and filtering of experimentally determined data and enable the comparison between test and calculation. The program consists of two parts: the material and component information system on the one hand and the calculation methods for service life prediction on the other. The information system was developed on the basis of the Oracle relational database management system. The information system contains both test and calculation results - 'real' and 'synthetic' data - in an otherwise identical database structure, which makes it easier to compare this data. Developed data structures currently cover the area of static and cyclic material and component data, as well as general material information. The concept of the information system already provides for the possibility of extending it to applications from fatigue fracture mechanics and the high-temperature range. This information system can be filled with application-specific data by the user. The calculation methods for service life prediction are essentially based on the local concept and the nominal stress concept. For the first time, the program also supports the numerical fatigue analysis of multi-axial, non-proportionally stressed components (based on the local concept). In particular, methods for simulating the deformation behavior under multiaxial stresses have been reprocessed and further developed. The program can be used on workstations on which Oracle is installed. It requires approx. 20 MB main memory for the overall functionality. Final report Scope of report:
