Consecutive strain steps and intermediate anneals slightly decrease the tensile and yield strengths. There is no influence of the material batch. A representative set of true stress–strain curves of these experiments are presented in Fig. 2. The initial material was in T3 condition i.e. it ...

Finally, based on the numerical method, a crack extension length calculation tool was developed to reveal the “fluctuation phenomenon” formation mechanism in the test curve and the “intersection phenomenon” in the fitted curve of the crack growth rate test results. Experiment Basic mechanical ...
The material properties, needed as input data for the simulation, were determined in isothermal tensile tests at different temperatures (500, 600, 700 and 800 °C) and strain rates (1.0, 0.1, 0.01 1/s). The calculated forming limit curves for these tem-peratures show a low deviation using...

The calculation of the strain value in bending, the minimum bend radius, the bend allowance, etc., may still be effected with the simplified equations that are normally used for macro/miniature-parts. These, however, need to include considerations concerning size effects. Similarly in the case ...
