!
! ************* user subroutine for defining material behavior **************
!
!
!CAUTION: Due to calculation of the Deformation gradients, Stretch Tensors and
! Rotation tensors at previous and current states, the analysis can be
! computationally expensive. Please use the user subroutine -> hypela
! if these kinematic quantities are not needed in the constitutive model
!
!
! IMPORTANT NOTES :
!
!
! (1) You must include the -> process,1,1,1, card in the parameter section
! of MARC input deck.
!
! (2) For total Lagrangian formulation use the -> 'large disp' card in the
! parameter section of MARC input deck.
! For updated Lagrangian formulation use the -> 'large disp' and 'update'
! cards in the parameter section of MARC input deck. However for any
! large strain calculation (whether elasticity or inelasticity) must entail
! the use of 'finite' parameter card also.
!
! (3) For Plasticity, the 2nd or 3rd cards in 'geometry' option in the model
! definition sections must be flagged for correct behavior in incompressible
! deformation.
!
! (4) The kinematic quantities are calculated for the following continuum
! elements (both lower and higher order) :
! plane stress, plane strain, generalized plane strain, axisymmetric,
! axisymmetric with twist and brick elements.
!
!
!
!
! d stress strain law to be formed
! g change in stress due to temperature effects
! e total strain
! de increment of strain
! s stress - should be updated by user
! t state variables (comes in at t=n, must be updated
! to have state variables at t=n+1)
! dt increment of state variables
! ngens size of stress - strain law

! nn integration point number
! kc layer number
! mats material identification number
! ndi number of direct components
! nshear number of shear components
! disp incremental displacements
! dispt displacements at t=n (at assembly, lovl=4) and
! displacements at t=n+1 (at stress recovery, lovl=6)
! coord coordinates
! ncrd number of coordinates
! ndeg number of degrees of freedom
! itel dimension of F and R, either 2 or 3
! nnode number of nodes per element
! jtype element type
! lclass element class

! at t=n+1 :
!
! ffn1 deformation gradient
! frotn1 rotation tensor
! strechn1 square of principal stretch ratios, lambda(i)
! eigvn1(i,j) i principal direction components for j eigenvalues
!
! The following operation obtains U (stretch tensor) at t=n+1 :
!
! call scla(un1,0.d0,itel,itel,1)
! do 3 k=1,3
! do 2 i=1,3

! IMPORTANT NOTES :
!
! (1) F,R,U are only available for continuum and membrane elements (not for

!
! (2) For total Lagrangian formulation use the -> 'Elasticity,1' card(=

! For updated Lagrangian formulation use the -> 'Plasticity,3' card(=
! update+finite+large disp+constant d) in the parameter section of
