! ************* 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) F,R,U are only available for continuum and membrane elements (not for
! shells and beams).
!
! (2) For total Lagrangian formulation use the -> 'Elasticity,1' card(=
! total Lagrange with large disp) in the parameter section of input deck.
! For updated Lagrangian formulation use the -> 'Plasticity,3' card(=
! update+finite+large disp+constant d) in the parameter section of
! input deck.
!
!
! d stress strain law to be formed
! g change in stress due to temperature effects
! e total elastic 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
! n element number
! nn integration point number
! kcus(1) layer number
! kcus(2) internal layer number
! matus(1) user material identification number
! matus(2) internal 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
! ifr set to 1 if R has been calculated
! ifu set to 1 if strech has been calculated
!
! at t=n :

!********************************************************************
! This is the Marc material routine
!********************************************************************
!
! ************* 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) F,R,U are only available for continuum and membrane elements (not for
! shells and beams).
!
! (2) For total Lagrangian formulation use the -> 'Elasticity,1' card(=
! total Lagrange with large disp) in the parameter section of input deck.
! For updated Lagrangian formulation use the -> 'Plasticity,3' card(=
! update+finite+large disp+constant d) in the parameter section of
! input deck.
!
!
! d stress strain law to be formed
! g change in stress due to temperature effects
! e total elastic 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
! n element number
! nn integration point number
! kcus(1) layer number
! kcus(2) internal layer number
! matus(1) user material identification number
! matus(2) internal 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
! ifr set to 1 if R has been calculated
! ifu set to 1 if strech has been calculated
!
! at t=n :
!
! ffn deformation gradient
! frotn rotation tensor
! strechn square of principal stretch ratios, lambda(i)
! eigvn(i,j) i principal direction components for j eigenvalues
!
! 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
! do 1 j=1,3
! un1(i,j)=un1(i,j)+dsqrt(strechn1(k))*eigvn1(i,k)*eigvn1(j,k)
