The elastic modulus, also known as the modulus of elasticity, or Young's modulus, is essentially a measurement of the stiffness of a material. Thus it is commonly used in design and engineering applications.
An elastic modulus also known as modulus of elasticity is a quantity that measures an object or substance's resistance to being deformed elastically i.e., non-permanently when a stress is applied to it.
The modulus of elasticity, also known as tensile elastic modulus or Young's modulus, is the stress required to produce unit strain. The modulus is measured by pulling a sample of the cured material in a tensile-testing machine while measuring the change in length by attaching an extensometer to the sample.
The plastic section modulus is used to calculate the plastic moment, M p, or full capacity of a cross-section.The two terms are related by the yield strength of the material in question, F y, by M p =F y *Z. Plastic section modulus and elastic section modulus are related by a shape factor which can be denoted by 'k', used for an indication of capacity beyond elastic limit of material.

RE: Elastic section modulus S vs. plastic section modulus Z ajk1 Structural 29 Jun 11 10:34 I agree with what BARetired said, but be careful that the section meets the requirements for LSD including symmetry.
The modulus of elasticity also known as the elastic modulus, the tensile modulus, or Young's modulus is a number that measures an object or substance's resistance to being deformed elastically i.e., non-permanently when a force is applied to it.
Engineers use the section modulus of the cross-section of a beam as one of the determinants of the beam's strength. In some cases, they employ the elastic modulus under the assumption that after a deforming force is removed, the beam returns to its original shape.
Elastic modulus is the ratio of stress, below the proportional limit, to the corresponding strain. It is the measure of rigidity or stiffness of a material.
A plastic section modulus is a geometric property for a cross section of an object generally used in materials in which plastic behavior can be observed.
The elastic section modulus assumes the section remains elastic. The plastic section modulus assumes the entire section yields. Elastic modulus is the steel modulus based on the stress strain curve before yielding. The plastic modulus is after yielding. I hope it helped, Thankyou
In this post, I will discuss the second example in our steel design course covering the analysis and design of beam members. The goal of this steel design example is to calculate the elastic section modulus Sx , plastic section modulus Zx , and shape factor f for a built up T-shape.
plastic section modulus correspond to Equations 2 to 13 given above. There must be as many sets of formulas, arranged in rows in the spreadsheet, as there are rectangles into which the cross section is divided. Assuming that the cross section to be
Tensile Modulus - or Young's Modulus alt. Modulus of Elasticity - is a measure of stiffness of an elastic material. It is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed.
Elastic modulus is the steel modulus based on the stress strain curve before yielding. The plastic modulus is after yielding. Plastic section modulus Z for various shapes are given in the steel book.
This modulus accounts for local plastic deformation and resulting strain hardening or softening. The secant modulus is derived from the slope of a line connecting the origin of the stress-strain
Re: Young's Modulus for Plastic URGENT Q Goest's link takes you to a site with mechanical properties for >50,000 polymers. It would be more effective if you explained why the earlier answers are unsatisfactory instead of just continuing to bump the thread.
The elastic modulus is an important property to consider when selecting a material, just as important as yield strength, conductivity or formability. Although often overlooked, the elastic modulus is a critical material property which should be factored into the material selection process. As a partial guide, Table
