Elastoplastic Stress - Strain Conversion
Mohr's circle will work fine for elastic stress strain conversion. For plasticity you need to use incremental plastic strain theory or some other methodology. So basically to recap: - I have measured elastic-plastic strains experimentally - In the elastic region stress strain conversion is...- backdude

Elastoplastic Stress - Strain Conversion
Thanks for your answer. Just to clarify the crux of my problem is coming up with the principal strains. I have no problem getting the effective strain and calculating the effective stress, but doing the stress separation is what I'm having trouble with. Thanks in advance. Dave- backdude

Elastoplastic Stress - Strain Conversion
Hi Everybody, I am doing some experimental work on hole cold expansion and have measured the strains around a cold expanded hole. I have full field principal strains around the cold expanded hole and would like to convert these strains to stresses. I am looking for a clear analytical (i.e I...- backdude
