18 Jun 2015 This example works from first principle sectional analysis of a steel T beam section to compute: -elastic Moment and elastic section modulus -plastic Moment
Okay, before stating the differences between elastic and plastic section modulus, let me intuitively define what section section modulus is nothing but quantification of geometry of section, which is similar to your concepts of perimeter, area,
there are two types of section moduli, the elastic section modulus (S) and the plastic section modulus (Z). the elastic section modulus is defined as S = I / y, where I is the second moment of area (or moment of inertia) and y is the distance

modulus of elasticity - and Ultimate Tensile and Yield Strength for steel, glass, wood and other common materials. elasticity is a property of an object or material indicating how it will restore it to its original shape after distortion. Yield strength is defined in engineering as the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation.
elasticity is the property of solid materials to return to their original shape and size after the forces deforming them have been the coefficient that relates a particular type of stress to the strain that results is called an elastic modulus (plural, moduli). elastic . plastic, ♶ LDPE. plastic, ♷ PP, 1.5–2.0, 0.040. plastic, ♸ PS, 3.0–3.5, 0.040. plutonium, 97. porcelain, 0.55, 0.0055 . alcohol, methyl (wood), 225.5.
Young's modulus is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per Young's modulus is also used in order to predict the deflection that will occur in a statically determinate beam when a load is applied at a point in between the beam's supports. Other elastic Other such materials include wood and reinforced concrete. . Carbon fiber reinforced plastic (70/30 fibre/matrix, unidirectional, along fibre), 181, 26.3.
the elastic section modulus of a beam is the ratio of the cross section Area Moment of Inertia to its greatest distance from the neutral axis. Area moment of inertia - Square section. For a simple solid Square the section modulus can be
the difference in their values indicates the reserve in strength or moment resisting capacity that a section made from sufficiently ductile material possesses. the ratio between plastic and elastic section modulus is known as shape factor.
the plastic section modulus is used for materials where elastic yielding is acceptable and plastic behavior is assumed to be an acceptable limit. Designs generally strive to ultimately remain below the

When Designing a Beam another property used is section modulus (Z) also known as Sx. the elastic modulus is denoted by Z or Sx. To calculate Z, the distance (y) to the extreme fibres from the centroid (or neutral axis) must be found as that is where the maximum the Beams Shown are a wood and Steel Beams

This model considers the timber with an elastic-linear behavior under tensile and an elastic-plastic behavior under compression. the first part is a deterministic numeric model that calculates the curve of load-deflection of the reinforced beam. the differences in hygro-expansion and stiffness between the wood and reinforcing materials can lead to separation at the glue-line, or torsion failure in the
