DeformShape2dFrm_wDispIntp

Purpose

deformed shape of 2d frame element with cubic polynomials

Synopsis

[XYd,xyd] = DeformShape2dFrm_wDispIntp (xyz,ElemData,u,v,MAGF,nsub)

Description

DEFORMSHAPE2dFRM_wDISPINTP deformed shape of 2d frame element with cubic polynomials
  [XYd,xyd] = DEFORMSHAPE2dFRM_wDISPINTP (XYZ,ELEMDATA,U,V,MAGF,NSUB)
  The function returns the global coordinates of the magnified deformed shape
  of a 2d frame element under large end displacements in array XYd,
  and the local coordinates of the magnified deformed shape in array xyd.
  Input arguments are the end node coordinates in array XYZ, the element
  properties in cell array ELEMDATA, and the end node displacements in vector U.
  Optional arguments are the end deformations V for elements with releases
  or plastic hinges (these can be supplied in a data structure with fields VE or V),
  the magnification factor MAGF (default=10), and the number
  of intermediate points NSUB (default=100) for the deformed shape.
  and NSUB for the number of intermediate points for the deformed shape;
  The function uses Hermite cubic interpolation polynomials for the
  transverse displacements.
