Soil hardening for normally consolidated soil during undrained shearing
Hello ,
in David Muir's book Soil behaviour and critical state soil mechanics, I have understood that during undrained shearing for normally consolidated soil there is soil hardening, would someone explain that to me especially that in some other references soft soil undrained shearing is accompanied with strain softening
