Recent edit to Crack tip opening displacement
Hello, and thank you for your recent contribution. I appreciate the effort you made for our project, but unfortunately I had to undo your edit because I believe the article was better before you made that change. Feel free to contact me directly if you have any questions. Thank you! Epicgenius (talk) 03:03, 1 March 2014 (UTC)
