Materials selection for XL wind turbine support
2018-9-1 · The LEFM ΔK was calculated using the equation [45,50]: (1) Δ K = ∆ P (B √ W) × (2 + α) (1-α) 1. 5 × (0. 886 + 4. 64 α-13. 32 α 2 + 14. 72 α 3-5. 6 α 4) where ΔP is the applied cyclic load range, B is the specimen thickness, W is the width of the specimen, a is the crack length and α = a/W. The damage-tolerant design approach of ...
