Hallo,
schlussendlich habe ich mit einiger Hilfe hoffentlich die Lösung gefunden und eine Druckwürfelprobe modelliert. Für das Betonvolumen muss in WB ein Befehl eingefügt werden der folgenden Code enthält:

!Elementtypwechsel

et,matid,solid65 !ET, ITYPE, Ename, KOP1, KOP2, KOP3, KOP4, KOP5, KOP6, INOPR
!Defines a local element type from the element library

keyopt,matid,3,2 !KEYOPT, ITYPE, KNUM, VALUE
!Behavior of totally crushed unreinforced elements
keyopt,matid,6,3 !Concrete nonlinear solution output

keyopt,matid,1,0 !Extra displacement shapes
keyopt,matid,5,2

esel,s,mat,,matid !ESEL, Type, Item, Comp, VMIN, VMAX, VINC, KABS
!Selects a subset of elements

emodif,all,type,matid !EMODIF, IEL, STLOC, I1, I2, I3, I4, I5, I6, I7, I8
!Modifies a previously defined element

emid,remove,all !EMID, Key, Edges
!Adds or removes midside nodes

!>>>Bei Netz>>> Erweitert>>> Mittelknoten>>> Nicht beibehalten einstellen<<<

!Materialdefinition CONCRETE PROPERTIES C25/30
/Status,all !/STATUS,all
Mat,matid !MAT, MAT

!Isotrope Elastizitaet

mptemp,1,22.0 !MPTEMP, SLOC, T1, T2, T3, T4, T5, T6
MP,dens,matid,2500e-9 !MP, Lab, MAT, C0, C1, C2, C3, C4
MP,EX,matid,3.1e4 !Defines a linear material property as a constant or a function of temperature.
MP,NUXY,matid,0.2

!Beton/Concrete/solid65

TB,CONCR,matid,1 !TB, Lab, MAT, NTEMP, NPTS, TBOPT, EOSOPT, FuncName
!Activates a data table for material properties or special element input.
tbtemp,22.0 !TBTEMP, TEMP, KMOD
Tbdata,1,0.4,0.8,2.6,33 !TBDATA, STLOC, C1, C2, C3, C4, C5, C6

!Constant Meaning
!1 Shear transfer coefficients for an open *****.
!2 Shear transfer coefficients for a closed *****.
!3=ft Uniaxial tensile *****ing stress.
!4=fc Uniaxial crushing stress (positive).
!5 Biaxial crushing stress (positive).
!6=f1 Ambient hydrostatic stress state for use with constants 7 and 8.
!7=f2 Biaxial crushing stress (positive) under the ambient hydrostatic stress state (constant 6).
!8 Uniaxial crushing stress (positive) under the ambient hydrostatic stress state (constant 6).
!9 Stiffness multiplier for *****ed tensile condition, used if KEYOPT(7) = 1 (defaults to 0.6).

Die WB Hilfe und folgender Link http://www.ce.tuiasi.ro/~bipcons/Archive/211.pdf haben mir u.a. geholfen.
