Post-necking workflow

Introduction

The post-necking calibration workflow refers to the systematic approach used to characterize and model the behavior of metals beyond the necking stage of deformation. After a metal undergoes necking, it enters a phase of localized plastic deformation that can eventually lead to failure. Accurately capturing and predicting how metals behave in this post-necking region is crucial for understanding their structural integrity and ensuring the safety and reliability of metallic components in engineering applications

Pre-requisites

To use this workflow, a general overview of the Workflow applications and Workers are recommended in addition to basic introduction to Ansys LS-DYNA solver. Please contact support@d3view.com to get more information on these topics if you are unfamiliar with these topics.

Introduction to the Workflow User Interface

The workflow is available as part of the Workflow Library and is named as ‘103_Metals_Postnecking_Calibration’. The date of update of this workflow might change based on the build and it is recommended to use the latest workflow. When the workflow is opened, the user is presented with the following of the Workflow.

Purpose of the Workflow

This workflow is constructed to take an Engineering Stress Strain curve and provide a calibrated MAT24 card whose material behaviour up until and including the Post necking region is similar to that of the Test data.​
