Dec 11,2014·Hello-I am running a simulation of a simple brazed steel assembly; brazed at 1050°C.I believe the Young's Modulus will drastically change after brazing at this temperature since the annealed state is dead soft.My analyst colleague is using an annealed value for E of 15E-6 psi,which isnt much less than cold-drawn.Elasticity and Youngs Modulus (Theory,Examples,and Youngs modulus is the same for any materialyou could take a spoon or a girder; as long as they have the same youngs modulus and you knew their sizes,you could predict how much force would cause a certain amount of elastic deformation.Since stress is a unit of pressure (usually expressed in MPa,or ) and strain is dimensionless,Young How does the Youngs modulus change with rise in ·Which of the three modulus of elasticity Y,K and is possible in all the three states of matter (solid,liquid and gas)? asked in Physics by Tannu ( 53.0k points) fluid mechanics
Whether that applies to all metals I'm not sure,I was inquiring about Inconel 600.Intuitivly,at first,it would seem logical that E does change depending on a material's temper/work hardened state.You probably are aware that it does change with temperature.I am still trying to wrap my head around it not changing in the other cases.People also askWhy does Young ' s modulus decrease with temperature increase?Why does Young ' s modulus decrease with temperature increase?Young's modulus show rigidity of the material.when temperature increase then material start to become soft.Therefore elasticity decreases with rise in temperature.Was this answer helpful?With rise in temperature,the Young's modulus of elasticityRelationship between Young's modulus and temperature in Aug 01,2012·As the temperature increases,the Young's modulus decreases almost linearly up to the quartz transition at 573 °C.Then the Young's modulus strongly increases up to the test temperature (700 °C).The decrease of the Young's modulus as the temperature increases was expected at least if no phase transformation,i.e.,no structural changes occur.
On further rise in temperature there was a very sharp increase in the decrement.Of the investigated alloys of the nickel -- chromium -- tungsten system,containing from 0.97 to 6.44 at.% of molybdenum,the alloy with 6.44 at.% of molybdenum had the least value of Young's modulus.The Effects of Temperature Plastics TechnologyChanges in Temperaturesemi-crystalline Nylon 6Stress-Strain CurvesAbout The AuthorThis lack of a predictable and repeatable structure gives rise to a situation where changes in temperature always influence the mechanical properties of these materials.This phenomenon can be captured by performing mechanical tests at various temperatures on any given material.One of the simplest ways to capture the load-bearing properties of a material over a wide range of temperatures involves a method known as dynamic mechSee more on ptonlinePublished Jul 27,2011Temperature dependence of rubber elastic modulusWhy does the elastic modulus of rubber increase with temperature?

AbstractIntroductionThe Effect of Temperature on YoungSmodulusConclusionsAcknowledgmentThe study of effect of temperature on Youngs modulus is extremely important for the strength under high temperature and thermal shock properties of ceramics and refractories.When the temperature increases,the atomic thermal vibrations increase,and this will cause the changes of lattice potential energy and curvature of the potential energy curve,so the Youngs modulus will also change.And with the increase of temperature,the material will have a volume expansion.Thus we know that the change of YoungsSee more on hindawiCited by 51Publish Year 2011Author Weiguo Li,Ruzhuan Wang,Dingyu Li,Daining FangModeling of Young's modulus variations withof nickel with temperature.For pure nickel,the Youngs modulus evolves non-linearly with temperature,from room temperature up to 360C,corre- sponding to the Curie temperature of nickel.Why is the Young's modulus important?Mar 07,2020·Elastic Moduli can be of three types,Young's modulus,Shear modulus,and Bulk modulus.Does Young's modulus increase with temperature?

There is one thing about Young's modulus that I find unexpected and confusing.When certain solid materials,pure metal,steel or an alloy of a certain composition,gets strengthened by cold working or by heat treating,the Young's modulus stays exactly the same as before even though the yield strength of that material gets doubled,and the elongation gets reduced by an order of magnitude.
