Plastic Section Modulus Calculation

I second moment of area in 4 or mm 4. The plastic section modulus for a rectangular cross section can be determined by multiplying each section half e g the shaded area shown in figure 1 50 by the distance from its centroid to the centroid for the whole section. The method con sists in dividing the cross section into rectangles and arrang ing all calculations conveniently into a spreadsheet program.

Plastic section modulus calculation. The plastic section modulus depends on the location of the plastic neutral axis pna. The pna is defined as the axis that splits the cross section such that the compression force from the area in compression equals the tension force from the area in tension. The links below on the left are section modulus calculators that will calculate the section area moment of inertia properties of common shapes used for fabricating metal into various shapes such as squares rounds half rounds triangles rectangles trapezoids hexagons octagons and more.

P perimeter of shape in or mm. The plastic section modulus is the sum of the areas of the cross section on each side of the pna which may or may not be equal multiplied by the distance from the local centroids of the two areas to the pna. The plastic modulus also known as the plastic section modulus is a theoretical tool used in structural engineering to quantify the strength of beams and how those beams deform under stress.
