minus-squareLeftRedditOnJul1@lemmy.worldcakelinkfedilinkEnglisharrow-up21·7 days agoP is the Proportional Limit, where it stops being linear, but remains elastic for a short while longer, meaning any deformation can still be recovered. E is the Elastic Limit, where it changes from elastic to plastic
