On using PM4silt for clay and using Undrained A and for sandy soils (PM4sand) Undrained A.is it correct to use this combination while studying for liquefaction analysis?
Since PM4sand and PM4 silt models are advanced constitutive models for dynamic analysis. I have read in one journal that for static analysis, they used Mohr-coulomb. Can we change the model after static analysis in one project? IS it possible?
Why liquefied points are observed in soil while using advanced constitutive models PM4sand and PM4silts before seismic loading? The liquefied points were observed in static phase only
