COMPUTE THE SECANT MODULUS OF THE CURVE

Computes the secant modulus of an input curve by calculating the slope of the line from the origin to each point on the curve. Use this worker to derive the secant stiffness or effective modulus from a stress-strain or force-displacement curve.

When to use

Classification: process.

Inputs

Label ID Type Default Required Description
Curve To Be Derived curvetobederived vector   Input X-Y curve (e.g. stress-strain or force-displacement) from which the secant modulus will be computed at each point; accepts any vector curve pair.

Outputs

Label ID Type Description
curve_secant_modulus_output_1 curve_sm_output_1 vector Output X-Y curve of the secant modulus values, where each Y value is the ratio of the ordinate to the abscissa (e.g. stress/strain) at the corresponding input point.
