Method & Assumptions
- Linear elastic beam theory is assumed.
- Small deflection theory is assumed.
- Material properties are homogeneous and isotropic.
- Shear deformation is neglected.
- Loads are static and applied within the elastic range.
- Beam self-weight is not included unless entered as a load.
