Section Moduls

Section modulus of a beam will be defined as the ratio of area moment of inertia of the beam about the neutral axis or centroidal axis of the beam subjected to bending to the distance of the outermost layer of the beam from its neutral axis or centroidal axis.

Section moduls. Hull girder section modulus is a well accepted parameter measuring the longitudinal bending strength of ships. Section modulus is a geometric property for a given cross section used in the design of beams or flexural members. The stress in the outermost section of beam is computed with the help of section modulus.

Other geometric properties used in design include area for tension and shear radius of gyration for compression and moment of inertia and polar moment of inertia for stiffness. This modulus is perhaps the single most important design parameter describing hull girder strength. Any relationship between these properties is highly dependent on the shape in question.

Other geometric properties used in design include area for tension radius of gyration for compression and moment of inertia for stiffness. Section modulus calculators 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. Hull girder section modulus to the deck often determines the bending strength of the entire hull girder.
