Hello Fellow Stressers,

There is a formula for one component of axial stress in ISO 14692 2017. It is given as (Do/2C)/E.

where:

Do = Pipe OD
C = Curve Radius
E = Elastic Modulus

I have two questions:

1) Shall the formula be written as Do/2C/E since Do/2C will be unitless and E will be in Mpa?

2) Is this a compressive axial stress for a curved pipe? How the formula was derived?

Your response is highly appreciated. Please correct any wrong statement I've made.

Thanks & Warm Regards,
