Specification of stress-strain relation of pipe material (Input Table)
Through the input data table SIGEPS the applicable stress-strain relation for the pipe material is provided.
The pipe material may vary along the pipeline. Several stress-strain relations are available to be used in material non-linear calculations (only possible within module M). The default check strain is the allowable strain from NEN 3650:
CHKEPS = 7 ‰ if Re ≤ 360 N/mm2
CHKEPS = 5 ‰ if Re > 360 N/mm2.
