What Is Initial Tangent Modulus? The initial tangent modulus is the slope of the initial straight line portion of the stress-strain curve, while the secant modulus is the slope of the line from zero deviator stress to a de- viator stress equal to one-half or one-third of the peak deviator stress (Lambe and Whitman 1969).

What Is Secant And Tangent Modulus? The tangent modulus can be taken at any point on the stress-strain curve. … The secant modulus represents the actual deformation at a selected point. Figure 3 shows that the secant modulus is drawn from the origin to any point on the stress-strain curve. What does tangent modulus tell
