Finite Element Analysis.

Finite Element Analysis (FEA) is a method for simulating how products interact with real-world forces. Will a product function as designed or break to cause injury?  FEA creates behavior models of mechanical stress, vibration, and heat transfer. BEAR possesses the capability to analyze complex and dynamic problems. FEA and 3-D Analysis eliminates the added expense of animation. We provide analysis, test results, and graphic representations in the form of photo-quality prints or computer video files at no additional cost. Images are formatted for viewing on all platforms and project well in courtroom settings using a digital projector.

Previous assignments.

irrigation pipe

The scanned image on the left represents a metal pipe imbedded in a plastic pipe underground. The investigation involved measuring dynamic loads of water pressing on the mechanical components of the pipe. The 3D model reveals that the spacing between the pipes concentrated stress in the outer pipe near the connection of the two pipes. The model also examined the stiffness of soil surrounding the pipe with the FEA model.


Playground accidents can occur from unforeseen equipment failure involving swings, slides, climbing frames, metal bars, and merry-go-rounds. Slides

and rope-plank swing failures can cause backward falls resulting in injuries. The scan to the left shows the 3-D model of a slide detailing the stress distribution of the frame, which determined whether or not the equipment was strong enough, to support the weight of multiple children.  

helicopter engine 

The image to the left represents a detailed image of contact stress analysis of the sleeve assembly of the rocker arm of a helicopter engine. The FEA analysis demonstrates the sleeve generated high stresses at the point of contact due to both bolting and system loads.This was compelling evidence that indicated one or more design element of the helicopter engine was at fault and in need of modification.

300 foot tower

The FEA analysis to the left reveals the transition section of a 300-foot water tower, 12-feet in diameter. This study included an examination of heat treatment of the welds combined with wind loading. As a rapid data capture process, FEA can deliver results.

offshore oil platform

BEAR engineers perform fracture assessments on offshore oiland gas platforms located in U.S. waters as well as the North Sea, the Caribbean and the Gulf of Mexico, all of which are vulnerable to severe hurricane forces. Bear inspected, laser-scanned and analyzed the Unimar platform after Hurricane Katrina wreaked havoc in 2005.


amusement park rides

Analyzing a large-scale structure is difficult in real time. FEA provides a solution. The image to the left shows the 3D model of a water slide at an amusement park in Northern California, created to locate fatigue provide fracture analysis.
