A design optimization study makes all kinds of sense on paper. Why wouldn’t you want your product to be the strongest, lightest, and most cost effective design possible? Why wouldn’t you want to have a way to quickly and accurate predict how your product will react to variations due to manufacturing tolerances, material quality, and loading? The tools to accomplish this are readily available and the internet is chock full of white papers, case studies, and success stories to support the methods. It should be a no-brainer, right?

Patrick Cunningham M.S.M.E. Senior Engineering Managert:/ f:203.758.2914203.758.2965
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
Bachelor of Science, Mechanical Engineering, Northeastern University

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.
