Stress check

The stress calculation for a numerical section is as follows:

with

 σvm

the VonMises stress, the composed stress

 σtot

the total normal stress

 τtot

the total shear stress

 σN

the normal stress due to the normal force N

 σMy

the normal stress  due to the bending moment Myy around y axis

 σMz

the normal stress due to the bending moment Mzz around z axis

 τVy

the shear stress due to shear force Vy in y direction

 τVz

the shear stress due to shear force Vz in z direction

Ax

the sectional area

Ay

the shear area in y direction

Az

the shear area in z direction

Wy

the elastic section modulus around y axis

Wz

the elastic section modulus around z axis
