For a small stress,the relation between stress and strain is linear.The elastic modulus is the proportionality constant in this linear relation.Tensile (or compressive) strain is the response of an object or medium to tensile (or compressive) stress.Here,the elastic modulus is called Youngs modulus.12.3 Stress,Strain,and Elastic Modulus - University stress = (elastic modulus) × strain.stress = (elastic modulus) × strain.12.33 As we can see from dimensional analysis of this relation,the elastic modulus has the same physical unit as stress because strain is dimensionless.12.3 Stress,Strain,and Elastic Modulus University In the linear limit of low stress values,the general relation between stress and strain is.stress = (elastic modulus) × strain.stress = (elastic modulus) × strain.As we can see from dimensional analysis of this relation,the elastic modulus has the same physical unit as stress because strain is dimensionless.12.4 Stress,Strain,and Elastic Modulus (Part 1 We can also see from Equation 12.4.4 that when an object is characterized by a large value of elastic modulus,the effect of stress is small.On the other hand,a small elastic modulus means that stress produces large strain and noticeable deformation.

Among materials with identical elastic limits,the most elastic is the one with the lowest elastic modulus.When the load increases from zero,the resulting stress is in direct proportion to strain in the way given by Equation 12.4.4,but only when stress does not exceed some limiting value.For stress values within this linear limit,we can describe elastic behavior in analogy with Hookes law for a spring.2 One-Dimensional Elasticity - AucklandEquation of Equilibrium (2.1.1a) dx du = Strain-Displacement Relation (2.1.1b) =E Constitutive Equation (2.1.1c) where E is the Youngs modulus, is the density and b is a body force (per unit volume).The unknowns of the problem are the stress ,strain and displacement u.2.2.1 Isothermal Small Strain ElasticityEqn.2.1.12 is the stress-strain equation for an anisotropic linear elastic material.The rate form is formally ij =Dijkl kl (2.2.14) For a nonlinear material is no longer quadratic,and the instantaneous modulus tensor is a function of the strains.If one starts by proposing the rate form of the elastic law,with a given modulus functionAuthor OpenStaxPublish Year 201612.5 Stress,Strain,and Elastic Modulus (Part 2 Jan 09,2017·When the bulk stress increases,the bulk strain increases in response,in accordance with Equation 12.4.4.The proportionality constant in this relation is called the bulk modulus,B,or.(12.5.3) B = b u l k s t r e s s b u l k s t r a i n = p V V 0 = p V 0 V.

The elastic modulus is the constant of proportionality between the stress and the strain.For sufficiently small stresses,the stress is directly proportional to the stress.It depends on the material being deformed.It also depends on the nature of the deformation.The elastic modulus,in general,relates what is done to a solid object to how thatChapter 6 Mechanical properties of metalsElastic Shear modulus,G G = G Other elastic properties simple torsion test M M Special relations for isotropic materials 2(1 +) E G = 3(1 2) K = Elastic Bulk modulus,K pressure test Init.vol =V o.Vol chg.= V P PP P = - K V V o P V K V o Comparison of Youngs moduli 0.2 8 0.6 1 Magnesium,Steel Platinum Characterization of polymeric foams - TU 12 4stress strain and elastic modulus part 1eThe modulus found here,is the modulus at small strains.As the elastic distortion increases,the axial load on a cell increases.This exerts an additional moment on the bent edge and in compression the modulus will decrease.So the part of the stress-strain response which is called linear elastic is concave downwards.Elastic Modulus of Concrete - LinkedInJan 22,2017·Based on the types of stress (tension,compression or shear) and strain,including the direction,different types of elastic modulus can be identified as detailed below.1.Youngs Modulus
