TABLE OF CONTENTS In the design of components with calculation temperatures below the creep range, the following five design checks have to be considered:
Gross Plastic Deformation Design Check (GPD-DC),
Progressive Plastic Deformation Design Check (PD-DC),
Stability Design Check (S-DC),
Fatigue Design Check (F-DC), and
Static Equilibrium Design Check (SE-DC).
In the design of components with calculation temperatures in the creep range, the following three design checks have to be considered additionally:
Creep Rupture Design Check (CR-DC),
Excessive Creep Strain Design Check (ECS-DC), and
Creep Fatigue Interaction Design Check (CFI-DC).
While work on these design checks in the sub-group Design Criteria of TC 54 WG C and the enquiry procedure has been completed, the required discussion is ongoing and the voting procedure is as yet far away. Therefore, this book is limited to load cases with calculation temperatures below the creep range.
The range of calculation temperatures for which creep related design checks are not required is given by the calculation temperatures for which the 0.2%-proof stress is not larger than both of the following two values,
the product of 1.2 and the creep rupture strength at calculation temperature and for the relevant lifetime,
the product of 1.5 and the 1% creep strain strength at calculation temperature and for the relevant lifetime.
The designations creep rupture strength and 1% creep strain strength refer to mean values, as specified in the material standard, for which a scatter band of experimental results...
