What Is the Cantilever Impact Dynamic Load Factor (DLF) Calculator?
When a mass drops freely from height h onto an elastic beam, kinetic energy conversion amplifies the resulting stress and deflection far beyond static self-weight.
The classical energy balance method computes the Dynamic Load Factor (DLF = 1 + √(1 + 2h/δ_st)), providing peak transient structural loading for mechanical design.
