Perfectly Plastic Post Necking Treatment

Overview

The CURVE_TRUETOEFFECTIVESTRESS worker now includes a new post necking treatment option called Perfectly Plastic (two-point yield curve, +1% at last strain). This enhancement provides a simplified method for defining post-necking material behavior.

Feature Description

A new option has been added under Post Necking Treatment to support perfectly plastic material behavior modeling after necking occurs.

The available option is:

Perfectly Plastic (two-point yield curve, +1% at last strain)

This treatment generates a simplified two-point yield curve with an additional point defined at 1% beyond the final strain value.
