load step

EK103

The secant stiffness method requires secant flexural and axial stiffnesses to be updated with each iterative cycle of the load step. This method differs to the Newton-Raphson and modified Newton-Raphson […]

EK102

Calculation procedures for the modified Newton-Raphson method are the same as for the Newton-Raphson method, except the stiffnesses for the first cycle are held constant for each iterative cycle of […]

EK101

In a Newton-Raphson method at the start of the load step, element stiffnesses are set to the values from the end of the previous step.
