二楼找到的程序，我也搜到了。只是看不太明白，刚开始学ABAQUS
我搜到的完整版本如下：
c User subroutine VUMAT
subroutine vumat (
c Read only -
* jblock, ndir, nshr, nstatev, nfieldv, nprops, lanneal,
* stepTime, totalTime, dt, cmname, coordMp, charLength,
* props, density, strainInc, relSpinInc,
* tempOld, stretchOld, defgradOld, fieldOld,
* stressOld, stateOld, enerInternOld, enerInelasOld,
* tempNew, stretchNew, defgradNew, fieldNew,
c Write only -
* stressNew, stateNew, enerInternNew, enerInelasNew )
c
include 'vabua_param.inc'
c
dimension jblock(*), props(nprops),density(*), coordMp(*),
1 charLength(*), strainInc(*),
2 relSpinInc(*), tempOld(*),
3 stretchOld(*),
4 defgradOld(*),
5 fieldOld(*), stressOld(*),
6 stateOld(*), enerInternOld(*),
7 enerInelasOld(*), tempNew(*),
8 stretchNew(*),
9 defgradNew(*),
1 fieldNew(*),
2 stressNew(*), stateNew(*),
3 enerInternNew(*), enerInelasNew(*)
c
character*80 cmname
parameter (
* i_umt_nblock = 1,
* i_umt_npt = 2,
* i_umt_layer = 3,
* i_umt_kspt = 4,
* i_umt_noel = 5 )
call vumatXtrArg ( jblock(i_umt_nblock),
* ndir, nshr, nstatev, nfieldv, nprops, lanneal,
* stepTime, totalTime, dt, cmname, coordMp, charLength,
* props, density, strainInc, relSpinInc,

* stressOld, stateOld, enerInternOld, enerInelasOld,
* tempNew, stretchNew, defgradNew, fieldNew,
* stressNew, stateNew, enerInternNew, enerInelasNew,
* jblock(i_umt_noel), jblock(i_umt_npt),
* jblock(i_umt_layer), jblock(i_umt_kspt))
return
end
c
subroutine vumatXtrArg (
c Read only -
* nblock, ndir, nshr, nstatev, nfieldv, nprops, lanneal,

* stressOld, stateOld, enerInternOld, enerInelasOld,
* tempNew, stretchNew, defgradNew, fieldNew,
c Write only -
* stressNew, stateNew, enerInternNew, enerInelasNew,
c Read only extra arguments -
* nElement, nMatPoint, nLayer, nSecPoint )
include 'vaba_param.inc'
c
dimension props(nprops), density(nblock), coordMp(nblock,*),
1 charLength(nblock), strainInc(nblock,ndir+nshr),
2 relSpinInc(nblock,nshr), tempOld(nblock),
3 stretchOld(nblock,ndir+nshr),
4 defgradOld(nblock,ndir+nshr+nshr),
5 fieldOld(nblock,nfieldv), stressOld(nblock,ndir+nshr),
6 stateOld(nblock,nstatev), enerInternOld(nblock),
7 enerInelasOld(nblock), tempNew(nblock),

9 defgradNew(nblock,ndir+nshr+nshr),
1 fieldNew(nblock,nfieldv),
2 stressNew(nblock,ndir+nshr), stateNew(nblock,nstatev),
3 enerInternNew(nblock), enerInelasNew(nblock)
c
c Documentation of extra arguments:
c nElement: Array of internal element numbers
dimension nElement(nblock)
c nMatPoint: Integration point number
c nLayer : Layer number for composite shells and layered solids
c nSecPoint: Section point number within the current layer
c
character*80 cmname

return
end
为什么VMAT里面是jblock,不是nblock？尤其是这段
parameter (
* i_umt_nblock = 1,
* i_umt_npt = 2,
* i_umt_layer = 3,
* i_umt_kspt = 4,
* i_umt_noel = 5 )
call vumatXtrArg ( jblock(i_umt_nblock),...
不明白怎么就获取积分点的单元信息了。 |
