Principal stress and maximum shear stress calculator was developed to calculate principal
stresses, maximum
shear stresses, stress angles and Von Mises stress at a
specific point for plane stress (σ_{z}=τ_{zx}=τ_{zy}=0). Mohr's Circle is also drawn
according to input parameters.
The formulas used for the calculations are given in the
"List of Equations"
section.
Calculator:
Note: Use dot "." as decimal separator.

Maximum principal stress (σ_{max}) 


MPa

Minimum principal stress (σ_{min}) 


Maximum shear stress* (τ_{max}) 


Average principal stress (σ_{avg}) 


Von Mises stress (σ_{mises}) 


Angle of principal stresses (θ_{p}) ** 


deg 
Angle of maximum shear stress (θ_{s}) ** 


Note 1:
*Maximum shear stress given in results is the maximum inplane shear stress. For
outplane shear stress, check 3D stress analysis.
Note 2:** There are 2 values for this parameter. The first value is shown in the table and the other value is 90°
apart from the first one.
