Mesh Settings

  • Using curvature-based mesh

  • Using h-adaptive method with mesh coarsening enabled

Mesh Convergence

Material yield strength: 460 MPa

Brake + Right Turn

  • Max stress not converging, but stays within a range of 123-190 MPa < material yield strength (460 MPa) with SoF = 2.42 → PASS?

Recommendations

  • Could think about adding a fillet on countersink hole edge to add more material at high stress location? Would probably be hard to control while machining, though
