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.

  SHELL63 and SHELL181 have several differences. 1. SHELL181 is first order shear deformation shell, where as SHELL63 does not account for transverse shell energy 2. SHELL181 has finite strain capability, where as SHELL63 does not. 3. SHELL181 can have all applicable nonlinear materials, where as SHELL63 is linear. 4. SHELL181 accounts for stress stiffness in a more consistent way than does SHELL63. It accounts for with both membrane stresses, enhanced strain effects, and transverse shear stresses. 5. SHELL181 has a more advanced warping correction algorithm than SHELL63, so it less sensitive to warping. SHELL181 and SHELL63 should produce similar results for linear elastic isotropic material, small deformation, very small thickness, and small warping.
