Finite Element

Finite Element Analysis is a computerized numerical procedure for solving a continuum of mechanical problems with accuracy acceptable to engineers. Finite Element Analysis is often used in the design phase of a product to evaluate the stress levels and displacements in a part or an assembly prior to prototyping and testing. It is also used to evaluate parts and assemblies as part of a field failure analysis or a safety evaluation. Our engineers and technical staff have expertise in using Finite Element Analysis and solid modeling techniques to evaluate the structural integrity and dynamic response of mechanical components and assemblies in a variety of applications.

For example, Packer Engineering was contracted by E.H. Wachs of Lincolnshire, IL to perform structural finite element analysis of the Wachs Subsea Unified Mechanical Cutting System for Casing Abandonment.  This tool was designed to assist with removal of oil platforms in the Gulf of Mexico which were damaged by Hurricanes Katrina and Rita.  Large clamps grip the outer casing of a casing string and a strongback supports the loads as the casing layers are cut.  The structure was optimized to handle compression, tension moment and torsion loads due to the release of energy as the layers of the casing string are cut.

Depending on the needs of our client, we provide a full range of finite element services including:

• Linear and Non-Linear Stress Analysis
• Vibration Analysis
• Fracture Analysis
