WebThe theory itself started with Kirchhoff [ 9, 10] in 1892 and Clebsch and Love [ 11] who considered small deformation of thin rods within the elastic range. The theory was developed under special assumptions that later became the approximations adopted by the so-called simple bending and torsion theory [ 12 ].
