CAESAR II Version
13

Specifies the long-term hoop stress at a 2:1 stress ratio. According to ISO 14692, hoop stress is twice the axial stress at a 2:1 stress ratio. That is, shl(2:1)= 2*sal(2:1). However, CAESAR II allows shl(2:1) to have a different value than twice of sal(2:1). In this case, CAESAR II displays a warning message in the Error Checker.

Typical units (depending on your unit system):

  • lb/in2

  • KPa

  • N/mm²

  • If you specify al(2:1) and leave hl(2:1) blank, CAESAR II assumes that hl(2:1) is equal to twice al(2:1) and displays a warning message in the error checker. For more information, see al(2:1).

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