Von Mises: Distortion Strain Energy Hypothesis
This hypothesis assumes that the material fails when the distortion strain energy exceeds a certain limit.
Tresca: Shear Stress Hypothesis
The hypothesis assumes that the failure is caused by the maximum shear stress.
Rankine: Normal Stress Hypothesis
This hypothesis assumes that the greatest principal stress leads to the failure.
Bach: Principal Strain Hypothesis
According to this hypothesis, the failure occurs in the direction of greatest strain. This statement is similar to the stress analysis according to Rankine. However, the principal strain is used instead of the principal stress in this case.
The RF-/STEEL EC3 add-on module can perform the design of fillet welds for all parametric, welded cross-sections of the cross-section library.
- Normal stresses σx from axial force and bending
- Shear stresses τ from shear force and torsion
- Equivalent stresses σv with comparison to limit stress
- Stress ratios related to equivalent stresses
- Normal stress σx from unit normal force N
- Shear stress τ from unit shear forces Vy , Vz , Vu , Vv
- Normal stress σx from unit moments My , Mz Mu , Mv
