WebJun 25, 2024 · maximum stress = Mmax* (h/2)/I = 180.78 N/mm^2 With the corrected constraint (see analysis 2 in the attached), Nastran is calculating 180.75 N/mm^2 for the maximum stress. Therefore, the results are identical. The von Mises stress at the center of the beam is also 180.75 MPa, so it is correct. WebVon Mises is one of the most commonly referred Equivalent stresses used in material science to estimate and materials strength and durability. The Von Mises relationship is most widely used by engineers and it has a great importance in data treatment and continuum calculations.
WebFor masticatory force F z, the maximum von Mises stress is considerably higher in compact bone (17.92 N/mm 2) than in the bone graft (8.29 N/mm 2). High stress values occur in the area of transition between the bone graft block, the augmentation, and the implant. Maximum von Mises stresses for P y and for L x may WebVon Mises Stress criterion is one of the widely used criteria for designing ductile material engineering components.
