4.5 CAM ELEMENT NO.5 WITH 2 NODES

The cam element is a simplification of the general beam element No.2: It has always a circular cross-cut. The element lies concentrically to the X axis, consequently local and global coordinates have the same direction. Inputs and calculations are simplified strongly through this. Like with the beam element the results are exact according to Bernoulli's bend theory and Hooke's law, and not approximate solutions like with the continuum elements.

Input:

CAD (see chapter 2.7.2): Line from node 1 to node 2

Z88I1.TXT

> Set KFLAG on 0 for cartesian coordinates
> 6 degrees of freedom in a node (Attention DOF5 (not right hand rule), see below)
> Element type is 5
> 2 nodes per element
> Cross-section parameter QPARA is the diameter of the cam

Z88I3.TXT

Cams No.2 have no influence. However, Z88I3.TXT must exist (with any content).

Results:

Deflections in X, Y and Z and rotations around X, Y and Z. Attention DOF5 (not right hand rule), see below
Stresses: SIGXX, TAUXX: Direct stress, shear stress, SIGXY1, SIGXY2: Bending stress in X-Y plane for node 1 and node 2, SIGXZ1 SIGXZ2: Bending stress in X-Z plane for node 1 and node 2
Nodal forces in X, Y and Z and nodal moments around X, Y and Z for each element and each node.
