ST7-1.57.40.2 Principal Stress Calculation for Beams with Circular Section
Strand7 calculates the principal stresses for beams of circular cross-sections only. The stress components included in this calculation are:
Fibre stress, which includes axial stress, and bending stresses in planes 1 and 2 (zz);
Shear stress due to torque (xy).
Shear stress in plane 1 (xz);
Shear stress in plane 2 (yz).
For the Pipe type element, Strand7 includes two additional stress components:
Pipe radial stress (RR);
Pipe hoop stress ().
The principal stress...
