Interface to beam structural elements.
This interface inherits from ISEL and it is inherited by IPileSEL.
|
pure virtual |
Get the integration data. The iData only exists for a plastic element, and this is indicated by the return value (true = plastic). shapeRect is true/false = rectangular/circular cross section. iDataSize is {ly or R, lz (rect only)} and iDataNum is {nx, ny or nr, nz or ntheta} with {or} denoting rect/circ.
|
pure virtual |
Get the integration data for integration point ip, where ip numbering starts at one. The iData only exists for a plastic element, and this is indicated by the return value (true = plastic). iData is {xi, a2, a3, wtComp} where (xi,a2,a3): abscissae (a2 is eta or r, a3 is zeta or theta with {or} denoting rect/circ); and wtComp: composite weight factor.
|
pure virtual |
Returns nodal force component at beam end. The nodal force is expressed using the force-moment sign convention which provides a continuous description of axial-force, shear-force, twisting-moment and bending-moment distributions across elements that make up a single beam-type structure by reversing the sign of the generalized force (expressed in the beam local coordSys) at end-0. Valid values for dof are 0, 1 or 2. Valid values for end are 0 or 1.
|
pure virtual |
Returns nodal force at beam end using the force-moment sign convention (see getNdForce(a,b) entry). Valid values for end are 0 or 1.
|
pure virtual |
Returns nodal moment at beam end using the force-moment sign convention (see getNdForce(a,b) entry). Valid values for end are 0 or 1.
|
pure virtual |
Returns the plasticity state indicators encoded as bits in the returned integer
for integration point ip where ip numbering starts at one.
For an elastic element, returns 0.
|
pure virtual |
Returns the plasticity state indicator names for integration point ip\n where ip numbering starts at one. If plastic element has not yielded then returns
an empty list. For an elastic element, returns "notPlastic".
|
pure virtual |
Returns percentage of IPs [0.0, 100.0] that have yielded (now or in the past) for
plastic materials. This value only makes sense for a plastic element, and this is
indicated by the return value (true = plastic).
|
pure virtual |
Gets the axial stress for int. point ip, where ip numbering starts at one.
The stress only exists for a plastic element, and this is indicated by the return
value (true = plastic).
|
pure virtual |
Gets the minimum and maximum axial stress for a plastic element. These values only exist
for a plastic element, and this is indicated by the return value (true = plastic).
The minimum and maximum values over all IPs are returned.
|
pure virtual |
Specify the shape and size of the beam cross section. Shape given by shapeRect (true/false = rectangular/circular). Size given by size. If rectangular shape then size[0] is ly and size[1] is lz. If circular shape then size[0] is radius and size[1] is not used. Specify the integration-point layout via nIPs, the number of IPs in each direc. [0] is x-direc. If rectangular shape then [1] is y-direc and [2] is z-direc. If circular shape then [1] is radial direc and [2] is circumferential direc. Internal stresses will be zeroed.
