Stress Around Holle Feature

  • Machine components are designed to withstand: applied direct forces, moments and torsion.
  • These loads may be applied gradually, suddenly, and repeatedly.
  • The design load is equal to the applied load multiplied by a combined shock and fatigue factor, Ks.
  • The average applied design stress must be multiplied by a stress concentration factor K
  • Calculated deflections are compared with required stiffness.
  • The material strength is compared with the maximum stress due to combinations of anticipated loads.

As shown below, + P = Tension and - P = Compression
