To this end it is important to make a clear distinction between the shakedown range and the ratcheting range. In cyclic plasticity more sophisticated hardening models have been suggested in order to model the strain evolution observed in ratcheting experiments. The hardening models used in shakedown analysis are comparatively simple. It is shown that shakedown analysis can make quite stable predictions of admissible load ranges despite the simplicity of the underlying hardening models. A linear and a nonlinear kinematic hardening model of two-surface plasticity are compared in material shakedown analysis. Both give identical or similar shakedown ranges. Structural shakedown analyses show that the loading may have a more pronounced effect than the hardening model.}, subject = {Biomedizinische Technik}, language = {en} } @inproceedings{StaatHeitzer2000, author = {Staat, Manfred and Heitzer, Michael}, title = {Direct static FEM approach to limit and shakedown analysis}, year = {2000}, abstract = {Safety and reliability of structures may be assessed indirectly by stress distributions. Limit and shakedown theorems are simplified but exact methods of plasticity that provide safety factors directly in the loading space. These theorems may be used for a direct definition of the limit state function for failure by plastic collapse or by inadaptation. In a FEM formulation the limit state function is obtained from a nonlinear optimization problem. This direct approach reduces considerably the necessary knowledge of uncertain technological input data, the computing time, and the numerical error. Moreover, the direct way leads to highly effective and precise reliability analyses. The theorems are implemented into a general purpose FEM program in a way capable of large-scale analysis.}, subject = {Einspielen }, language = {en} } @article{Staat2004, author = {Staat, Manfred}, title = {Plastic collapse analysis of longitudinally flawed pipes and vessels}, year = {2004}, abstract = {Improved collapse loads of thick-walled, crack containing pipes and vessels are suggested. Very deep cracks have a residual strength which is better modelled by a global limit load. In all burst tests, the ductility of pressure vessel steels was sufficiently high whereby the burst pressure could be predicted by limit analysis with no need to apply fracture mechanics. The relative prognosis error increases however, for long and deep defects due to uncertainties of geometry and strength data.}, subject = {Druckbeh{\"a}lter}, language = {en} } @misc{Gebhardt2005, author = {Gebhardt, Andreas}, title = {Lasertechnologie : Laser - Materialbearbeitung ; Grundlagen - Verfahren - Anwendungen}, year = {2005}, abstract = {Theoretische Grundlagen, Grundlagen der Materialbearbeitung mit Laserstrahlung, Aufbau und Funktion von Laser-Bearbeitungsanlagen, Laserstrahl-Schneiden, Laserstrahl-Schweißen, Laserstrahl-Bohren, Beschriften und Markieren mit dem Laser, Oberfl{\"a}chenveredeln mit dem Laser, Lasersicherheit, Umweltschutz}, language = {de} } @misc{Gebhardt2005, author = {Gebhardt, Andreas}, title = {{\"U}bungsklausur zum Fach Lasertechnologie}, year = {2005}, abstract = {{\"U}bungsklausur}, language = {de} } @misc{Gebhardt2005, author = {Gebhardt, Andreas}, title = {Zusammenfassung der Inhalte der Veranstaltung Lasertechnologie zur Vorbereitung auf die schriftliche Klausur}, year = {2005}, abstract = {Grundlagen und Anwendungen}, language = {de} } @misc{Gebhardt2005, author = {Gebhardt, Andreas}, title = {Rapid Prototyping : Werkzeuge f{\"u}r die schnelle Produktentwicklung}, year = {2005}, abstract = {Grundlagen der Rapid Prototyping-Verfahren Industrielle Rapid Prototyping Verfahren: Stereolithographie (SL), Lasersintern (SLS), Schicht- (Laminat) Verfahren (LLM), Extrusions-Verfahren (FLM), 3D-Printing (3DP) Abformverfahren und Folgeprozesse: Vakuumgießen, Gießharz-Werkzeuge, Vorserienwerkzeuge aus Aluminium}, language = {de} } @misc{Gebhardt2005, author = {Gebhardt, Andreas}, title = {Short course on rapid prototyping}, year = {2005}, abstract = {Rapid Prototyping Technology: Types of models, rapid prototyping processes, prototyper Fundamentals of rapid prototyping Industrial rapid prototyping technology: Stereolithography, (Selective) laser sintering ((S)LS), Layer laminate manufacturing (LLM), Fused layer modeling (FLM), Three dimensional printing (3DP)}, language = {en} }
