Nonlinear custom cross-sections
Analysis of physically nonlinear bars for which a cross-section of arbitrary shape and components is generated in the "Cross-section Design Toolkit" module. Elements with such a cross-section can be physically nonlinear step-type, iterative with unloading with initial stiffness and iterative without unloading.
