The permissible dynamic bending stress is used to calculate the permissible dynamic radial load and a safety factor for the bending stress amplitude. The stress is considered at the point where the maximal stress occurs.
The input value is a permissible alternating stress with is reduced by the mean stress influence coefficient ψ. The safety factor is calculated as
The permissible dynamic radial load is calculated so that a safety factor of 1 is reached.
