Specifies the long-term hoop stress for a partially restrained hydraulic (R_test) condition.

Typical units (depending on your unit system):

  • lb/in2

  • KPa

  • N/mm²

  • For information on failure envelope points, see Figure B.1 of ISO 14692-2:2017.

  • If you do not specify a value for h_R and a_R then the software uses a simplified failure envelope based on other defined envelope points: al(0:1), al(2:1), and hl(2:1).

  • The value of h_R must be less than the value of hl(2:1).
