We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

  3. Why don’t SHELL181 mid-surface results reflect plastic stress-strain curve? Due to transverse shear the mid-surface equivalent stress is higher than the top or bottom surface and the value being reported is far beyond the yield stress.

      Development explained that SHELL181 treats the transverse shear linearly. Plasticity is not considered. If transverse shear needs to be modeled with plasticity a 3d element is required. Possibly a 3d submodel could be used. It is somewhat rare in thin shells for the transverse shear to be the dominant stress.
