Stress-Strain Diagrams of Concrete

Calculates stress value of concrete given strain and material properties

Calculates stress value of concrete given strain and material properties using the model in the reference [1].

function Stress=CONCRETE(Strain,Properties)

%Input

Strain: Strain value

Properties: A vector defining concrete properties as shown (with posative values):

(1):Compressive strength

(2):Tensile strength

(3):Strain at stress=compressive strength

(4):Strain at stress=tensile strength

(5):Modulus of elasticity

Output

Stress: Stress value

Example file is also provided.
