Uniaxial compression strength versus hydrostatic / triaxial

    For typical metals used in construction I've seen the compression strength being used in various calculations. Typically I assume this is the uniaxial compressive strength. i.e. Say in a UTM with the specimen laterally loaded.

    Are there engineering situations where the hydrostatic compressive strength of materials is important? This strength seems much larger than the uniaxial strength & is tested in a setup where a piston & oil produce lateral uniform loadings on the test sample.

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
