A general form of Drucker-Prager type smooth and convex plastic potential. Part 1: Definition and features
Abstract
A general form of Drucker-Prager type plastic potential suitable forconcreteandsoilisproposed,allowingtodistinguishqualitative differencebetweenstressstateswithprevailingtensionfromthosewith dominantcompression.Thepotentialincludessixmaterial constantsandonearbitrarilychosenfunctiongdescribingdeviatoricsectionofthepotentialsurface.Theinfluenceoftheparametersontheshapeoftheconsideredyieldsurfaceisdiscussed.Theverificationofconvexityoftheproposedpotentialiscarriedoutinordertoimposeconditionsontheparameters and the unknown functiong. The calibration based on results oftypicaltestsforconcretepresentedintheliteratureisproposedandthevaluesofthecoefficientsaregivenoutinrelationtotheyieldlimitinuniaxial compression test for common proportions of yield limits for other basic tests
