How do vibration frequencies impact the fatigue life of PVC kinetic sculptures?

The fatigue life of PVC kinetic sculptures is significantly influenced by vibration frequencies, which determine the mechanical stress and wear over time. When exposed to consistent vibrations, PVC materials undergo cyclic loading, leading to micro-cracks and eventual structural failure. Higher frequencies often accelerate fatigue, reducing the sculpture's lifespan, while lower frequencies may cause gradual degradation. Factors like amplitude, material composition, and environmental conditions further modulate this effect. Understanding these dynamics helps artists and engineers design more durable kinetic sculptures, balancing aesthetic motion with long-term structural integrity. Proper damping techniques and material selection can mitigate fatigue, ensuring the artwork's longevity.
