Rectangular Beam Stress Strength Design Calculator to calculate normal stress, shear stress and Von Mises stress on a given solid rectangular cross section. Calculator also draws graphics of the stress variations with respect to distance from the neutral axis.
The transverse loading on a rectangular beam may result normal and shear
stresses simultaneously on any transverse cross section of the structural
rectangular beam. The normal stress on a given cross section changes with
respect to distance y from the neutral axis and it is largest at the farthest
point from the neural axis. The normal stress also depends on the bending moment
in the section and the maximum value of normal stress in rectangular beams
occurs where the bending moment is largest. Maximum shear stress occurs on the
neutral axis of the rectangular beam section where shear force is maximum.
The design of rectangular beams is generally driven by the maximum bending moment. In the case of short structural beams, the design may be driven by the maximum shear force.
Note: For more information on the
subject, please refer to "Design of Beams and Shafts for Strength" chapter of Mechanics of Materials
Note: V and M are the shear force and bending moment in a section as shown in
the figure.Visit "
Structural Beam Deflection and Stress Calculators". for shear force and bending moment calculations.
Note: Structural beam is assumed to be subjected a vertical shearing force in its vertical plane of symmetry.
Note: Use dot "." as decimal separator.
Note: Stresses are positive numbers, and these are stress magnitudes in the
beam. It does not distinguish between tension or compression of the structural
Von Mises Stress
Normal Stress: Stress acts perpendicular to the surface (cross section).

capacity of a cross-section to resist bending.
Saint Venant's Principle: Stresses on a surface which are reasonably far from
the loading on body are not notably modified if this load is changed to a static equivalent load. The distribution of stress and strain is altered only near the regions where load is acting.
Shear stress: A form of a stress acts parallel to the surface (cross section) which has a cutting nature.
Stress: Average force per unit area which results strain of material.
