Bending–torsional coupled dynamic response of axially loaded .

It should be also noted that the theory with bending–torsion coupling ignored does not give any torsional displacement of the composite beam as the composite beam is subjected to a bending force however the flexure–torsion coupled theory has predicted substantial torsional displacement due to the modal coupling as can be seen from Fig. 7 .

Polar moment of inertia - Wikipedia

Simply put the polar moment of inertia is a shaft or beam& 39;s resistance to being distorted by torsion as a function of its shape. The rigidity comes from the object& 39;s cross-sectional area only and does not depend on its material composition or shear modulus. The greater the magnitude of the polar moment of inertia the greater the torsional .
