BALLSHEAR
  Steve Groothuis (Micron Technology, Inc.)
  "I have uploaded a nice mechanical contact problem using solder and a shearing ram (original work is found in Huang, et al. ECTC paper). That paper spells out the material properties necessary to perform a rate-dependent mechanical load using ANSYS. Compare the paper's Figure 3 with the /POST26 plvar plot (excellent correlation with minimal data)."

BEAM176CROSS
  Sheldon Imaoka (ANSYS, Inc.)
  Simple example of new beam-to-beam contact capability in ANSYS 10.0 using CONTA176. (Note that version 10.0 or higher must be used.) Sample image of results.

CONTPRES
  Sheldon Imaoka (ANSYS, Inc.)
  Simple 2D example comparing SY (y-component of stress) at contact surface with CONTPRES (contact pressure). With surface-projection-based contact, results match very well, showing benefits of using surface-project-based contact (KEYOPT(4)=3 for 17x contact elements).

CURING
  Steve Groothuis (Micron Technology, Inc.)
  "Try this sample input file demonstrating VE cure simulation. The data originated from a Ph.D. dissertation ("Viscoelastic stress analysis and fatigue life prediction of a flip-chip-on-board electronic package.", PAUL B. KOENEMAN, Thesis (Ph.D.). University of Texas at Austin, Austin, TX 78712, USA, 1999. 113pp.)."

ELBOW290
  Sheldon Imaoka (ANSYS, Inc.)
  Attached is a simple, made-up example demonstrating use of ELBOW290 elbow element. There are 3 layers defining the pipe (plasticity and hyperelasticity). The pipe is rotated until local buckling occurs. An image of the file shape (showing the pipe in 3D) is here.

EXPANSION
  Sheldon Imaoka (ANSYS, Inc.)
  This is a description of an ANSYS Workbench 13.0 project and the use of the HSFLD242 (hydrostatic fluid) element. It is a fictitious model of the expansion of a tire and subsequent displacement-loading to a rigid surface (e.g., ground). The Workbench archived project is here.

GASKET
  Sheldon Imaoka (ANSYS, Inc.)
  Very simple example showing how to use element birth & death to include a non-uniform initial gap. Usually, initial gap for gasket material (TB,GASKET,,,,PARA) is assumed to be a uniform input. By using element birth and death while perturbing the nodes, one can include a non-uniform initial gap.

ICPKG
  Steve Groothuis (Micron Technology, Inc.)
  "An example of IC package assembly using element birth and death - a simple 5-step die attach, injection molding, and cool-down processes during IC packaging. (compliments to Bill Bulat on concept)"
Unzip the file and read in "icpkg.inp".

INTERP
  Vladimir Tkach (NPO Energomash)
  "This example interpolates stress-strain curve by polynomial function - Strain=A1+A2*StressA3*Stress^2, in temperature area between Proportional, Yield and Ultimate stresses and reads it into ANSYS db-file."

OFFSET
  Sheldon Imaoka (ANSYS, Inc.)
  Shows difference between geometric offset and contact offset (CNOF real constant), useful in interference fit problems (so you don't have to modify geometry iteratively).

SHELL-ABD
  Sheldon Imaoka (ANSYS, Inc.)
  Simple example showing how to calculate the A, B, D, and E matrices for general shell input for a single layer (homogenous) shell.
The A, B, D, and E matrices are the shell membrane, coupling, bending, and transverse shear stiffness relationships.
