Slope of The Non Linear Stress Strain Curve at Proof Stress

Dear All

Hi..

Can Any body tell Me The calculation of the E_t Tangent And E_s Secant Modules VAlues of the Stress Strain curve?...

i had go through some of graphs but i dont get it?..it will be help ful to understanfd the E_t And E_s?..

i had values of Stress and Strain and also a Stress strain curve available..

Plz do need ful..

Material Property Values

Dear All

I want to knnow what is the Strain VAlues at the SA-387(or 11/4 Cr 1/2 Mo Ni Si) plate at 940'F and in creep RAnge at time of 1000000 Hrs of loading...how to find Strain Values at SAme TEmp & Time and Diff loading of mtrls like 10,100, 1000 and So on..

Please Help...

Stress Defination

Hello All//

I am always confuing on that Stress is a point Function..and not Seen Physically Than Stress is a material Property or Material Behaviour?

Waiting For Answer..

Thanks..

MPC omega method

Hello All..

i am finding the MPC omega method for the devlopment of Isochronous curve..in which i am searching in the ASME catalogue but it will want 599$ so it will not affodable me...so anybody who will guide me..

Finding Books

Hi all

I want to Find Books For Non Linear Stress- Strain Curve,which Gives more Idea About the Plastic Region,and terms of Tangent modules(E_t) nad secant modules(E_s)...plz do needful and Reply...

Yours faithfully

WRC(welding Resarch code)

Dear

All

any body had idea about what is the WRC code anf from where it is available?i want to find one relation between Et(tangent modules)  ,Es(secant modules) and allowable comp.stress ?

if any one knows plz let me know..

Iso Chronous curve

Thanks Vijay

                  for giving me guide lines but my altimate aim is to the finding of devlopment of iso chronous curve for creep buckling.and for that while studing nonlinear strees strain curve we know that as in non linear stage the what is the value of stress and strain at time T=0 and time T=t? is the any formula for the Et and Es in non linear stress and strain?...and which procedure for calulation foe Et and Es?

Relation Between Et(tangent Modules) & Es(secant Modules) in non linear elastic plastic theory?

dear all

            is there any formaula or any theory by i can make a relation for the tangent and secent modules in the plastic region of the stress strain curve?....and also how to find Et and Es for the Alloy steel?.. if any body knows any thing than let me know soon..

warm regards
