4.9 TRUSS NO.9 IN PLANE
The truss element No.9 can take any location in the X-Y plane. It is the simplest element in Z88 and is calculated extremely fast. The truss elements matches Hooke's law exactly.
Input:
CAD (see chapter 2.7.2): Line
from node 1 to node 2
> KFLAG for cartesian (0) or polar coordinates (1)
> 2 degrees of freedom for each node
> Element type is 9
> 2 nodes per element
> Cross-section parameter QPARA is the cross-sectional area
of the truss
Trusses No.9 have no influence. However, Z88I3.TXT must exist
(with any content).
Results:
Displacements in X andY
Stresses: Normal stresses
Nodal forces in X and Y for each element and each node.
