Interface to shell structural elements.
This interface inherits from ISEL.
|
pure virtual |
Returns a anisotropic material property. If the shell does not have anisotropic property, this function return 0.0
. Valid values for parameter p(material-coefficient stiffness) are: 0 (C11), 1(C12) , 2 (C13), 3(C22), 4(C23) and 5(C33)
Valid values for parameter t are: 1 (membrane) and 2 (bending)
|
pure virtual |
Shell-type sels: Returns the stress in coupling springs at nd_idx and side.
If norm is true, returns normal stress, else returns shear stress.
Valid values for nd_idx are 0, 1 or 2.
Valid values for side are 0 (side 1) or 1 (side 2).
The computation is general and will work even if link assignments have been modified. Computes stress based on forces in all deformable directions of link at side.
|
pure virtual |
Returns the yield state for geogrids and liners: 0 = "No Yield" 1 = "Yielding Now" 2 = "Yield in Past"
|
pure virtual |
Returns membrane stress resultants Nx,Ny,Nxy (parameter memb) and bending stress resultants Mx,My,Mxy (parameter bend) for ONE ISOLATED element, in its local coordinate system: average stress resultants computed on each node, based on forces acting on it.
|
pure virtual |
Returns an isotropic material property
. Valid values for parameter propNo are: 1(Young's modulus) and 2(Poisson's ratio)
|
pure virtual |
Returns material property type
Return values are: 1 (isotropic), 2 (orthotropic), 3 (anisotropic)
|
pure virtual |
Returns a orthotropic material property. If the shell does not have orthotropic property, this function return 0.0
. Valid values for parameter p(material-coefficient stiffness) are: 0 (C11), 1(C12) , 2 (C22) and 3(C33)
Valid values for parameter t are: 1 (membrane) and 2 (bending)
|
pure virtual |
Returns the principal stress at location locCode.
Valid values for parameter locCode are: 0(centroid), 1(node-1) ,2 (node-2) and 3(node-3)
|
pure virtual |
Returns the symetric stress tensor at locacion locCode. Stresses are expressed in the global system.
The stresses are recovered at the current depth factor.
Valid values for parameter locCode are: 0(centroid), 1(node-1) ,2 (node-2) and 3(node-3)
|
pure virtual |
Returns the stress resultant at location locCode.
