træthedslevetiden
Træthedslevetiden, often translated as fatigue life, refers to the number of stress cycles a material can withstand before failure due to fatigue. Fatigue is a phenomenon where materials weaken and eventually fracture under repeated or fluctuating loads, even if these loads are well below the material's ultimate tensile strength. This gradual damage accumulation is a critical consideration in engineering design, particularly for components subjected to cyclic stress, such as aircraft wings, engine parts, bridges, and rotating machinery.
The træthedslevetiden is typically determined through experimental testing. Samples of the material are subjected to controlled
Factors influencing træthedslevetiden include the magnitude and type of stress (tensile, compressive, bending, torsional), the stress
