EK433
The torsional resistance of a beam twisting about its longitudinal axis is usually divided into: uniform (St. Venant) torsion and non-uniform (warping) torsion.
EK338
Principle of St. Venant states that the actual distribution of the load over the surface of its application will not affect the distribution of stress or strain on sections of […]
EK266
The discontinuity in the stress distribution in D-region, based St. Venant‘s principle, indicates that the stresses due to axial load and bending approach become linear at a distance approximately equal […]
EK220
Both components of torsion produce shear stresses parallel to the walls of the section, and their combined effects can locally be greater than the effects of St. Venant alone.
