Stress intensity factor using Ansys APDL for a 3D plate

Click For Summary

Discussion Overview

The discussion focuses on evaluating the stress intensity factor (SIF) for a 3D plate using ANSYS APDL, particularly in the context of applying out-of-plane shear forces and understanding how SIF varies along the thickness of the plate. Participants seek resources, tutorials, and insights related to this specific application in fracture mechanics.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant is seeking tutorials or notes on evaluating SIF for a 3D plate using ANSYS APDL.
  • Another participant requests clarification on the specifics of the inquiry and what research has already been conducted.
  • A participant specifies that they are applying out-of-plane shear force and wants to understand the variation of SIF along the thickness of the plate.
  • There is a question regarding whether the discussion pertains specifically to brittle material fracture mechanics.
  • A participant confirms that their focus is on brittle material fracture, specifically linear elastic fracture mechanics.
  • Some participants suggest that the original poster should actively contribute to the conversation and refer to ANSYS documentation for additional information.
  • It is noted that available tutorials for SIF evaluation are primarily for 2D plates, and the original poster is looking for resources specific to 3D plates.
  • A participant recommends a paper that seems relevant to the topic of 3D static and dynamic SIF computations using ANSYS.

Areas of Agreement / Disagreement

Participants express a lack of consensus on the availability of resources for 3D SIF evaluation, with some suggesting that existing materials are primarily focused on 2D scenarios. The discussion remains unresolved regarding the specific methodologies applicable to 3D plates.

Contextual Notes

Limitations include the potential dependence on specific definitions of SIF and the unresolved nature of how to adapt existing 2D tutorials to 3D scenarios.

Can you be more specific in what you're trying to do? What have you researched so far?

Thanks for your reply.

I am trying to evaluate SIF for 3D plate applying out plane shear force. I want to know how SIF is varying along the thickness.
 
Is this specific to brittle material fracture mechanics?

Yes, I am trying for brittle material fracture (Linear elastic fracture).
 
I did a little internet searching and found a couple of results, are you having trouble finding the information you need? We need you to actively contribute to this conversation if you're going to get anything out of it. ANSYS also has excellent documentation, what have you found in their help files?

Sure...
I have seen many tutorials for SIF evaluation. But all were for 2D plate. I am trying for 3D plate so that I can get variation of SIF along thickness.
