How to define contacts with erosion in Abaqus | Contact and Element deletion

Contacts are a very common feature in the simulation of many different phenomena. However, when the surfaces involved in the contact are modified during the simulation because of the erosion of damaged elements (e.g. impacts, machining processes...), the definition of contacts is not trivial. In this video you will learn two different strategies to define contacts in Abaqus when one of the parts is eroded and when both parts can be eroded. 00:00 - Intro and objectives 00:46 - Setup of the example (Python script) 03:12 - The problem of conventional contacts 06:19 - Case 1: Surface - Nodes 11:13 - Case 2: Internal surface - Internal surface 16:04 - Summary 16:42 - Outro Download the script used in the video from the blog post: https://tecnodigitalschool.com/how-to...
