Goodman Smith

Zhejiang Stellar Global Co., Ltd.

Goodman-Smith Calculator performs the calculation of the Goodman-Smith fatigue check diagram, permitting to key in geometrical, dimensional and finishing properties of the workpiece

Use:
  1. Insert data related to material, geometry, dimension and finishing
  2. Insert data related to application properties
  3. Visualization of Goodman-Smith diagram and load figure (sinusoidal just for representation purpose)
