  /   f:

Patrick Cunningham brings over 25 years of engineering experience to CAE Associates. 

Prior to joining CAE Associates in 1998, he worked in several industries including machine design of plastic and rubber processing equipment, high power ultrasonics and elevator design.  While in the R&D group at Branson Ultrasonics he was awarded two patents for rigid transducer mounting systems that are an industry standard today.  While at Otis Elevator in 1997, he received an award for individual effectiveness for his part in the development of a modeling environment used to design closed loop active suspension systems for elevator cars.    His current responsibilities include all phases of mechanical engineering consulting projects, technical support of the ANSYS products, software training, and organization of the yearly ANSYS product update seminars provided by CAE Associates.   Pat also provides applications support for sales of the ANSYS software products. 

In his free time, Pat is an avid cyclist and competes as a member of the Horst Engineering Master's Cycling team in both road and cyclo-cross disciplines.  During the winter months, he keeps himself busy as an assistant swim coach for his local high school.


Master of Science, Mechanical Engineering, Rensselaer Polytechnic Institute

Have you ever had to model a bolted interface on an assembly with an internal pressure? Consider a simple example, shown in Figure 1 above, of a bolted pipe connection under internal pressure. The goal is to maintain a seal between the pipe flanges and keep the connection from leaking. To accomplish this, a bolt pre-load is applied, prior to the pressure, that pushes the surfaces of the flanges together.

When two independent bodies interact under load in a finite element model, surface-to-surface contact elements are used by the more sophisticated FEA codes to manage the interaction. A typical surface-to-surface contact region consists of a pair of element types that are located on the outer faces the structural finite elements. On one body you will have contact elements whose job is to search for target elements on the opposing body. The contact elements will only search for targets of the same pair.
