Tensile Stress-Strain

  1. Apr 1, 2015 #1
    Hi
    If i have the stress-strain curve of concrete(compression) then how do i plot the SS curve for tension with reference with tangent modulus or secant modulus??

    what is the ultimate tensile strain of plain concrete?

    You cannot deduct SS curve for tension from compression curve.
    especially for concrete as tension and compression stress capabilities for this material are completely different.
    UTS compression for concrete is typically +/- 50MPa, depending on concrete quality/type ofc.
    UTs tension +/-5 MPa

    UTS = ultimate tensile strain and see my first post. Be sure to check what concrete quality you have and check google afterwards.

    there is something to plot the tension SS curve from secant modulus..???

    Yes, you can but it's not really a curve like the compression curve and technically you don't use the secant modulus.
