I have symmetry structure, bending of bolt with two plates., solved with linear elastic material with loading on +X direction in Abaqus.

My fatigue test loading is sinusoidal wave ( 1,-1).

Stresses from Abaqus combined with sinusoidal wave with SN curve in Fesafe, i get life/hotspot on bolt in +X direction say 1000 cycles, and life on -X direction on bolt is 1000000 cycles.

I expect  there will be symmetry
