- •
Formulation for the nonuniform warping dynamic analysis of beams.
- •
Beams under general external loading and boundary conditions are examined.

The proposed method employs a BEM approach and high accuracy is achieved.
- •
Shear lag phenomenon due to both torsion and shear is investigated.
- •
Comparison with FEM solid models demonstrates the accuracy of the method.
