  • Engineering analysis of mechanisms and machines
  • Product development and design
  • Prototype fabrication & rapid prototyping
  • Process failures
  • Failure cause and origin
  • Fire and explosion cause and origin
  • Testing:
    • Engines: dynamometer facility, up to 250hp
    • Vibrations: multiple access shake tables
    • Tensile, fatigue, impact strength testing
    • Controls system analysis
  • Legal services:
    • Expert witness testimony
    • Root cause analysis and scientific reports
    • Inter Partes Review (IPR), intellectual property design analysis, patent litigation
    • Evidence storage

The name "poly-X-engineering" encapsulates the idea behind the firm: "poly" describes our multidisciplinary nature, "X" highlights our continuous growth and our experience in legal expert work. Engineering is what we do. Click here to read more about polyX.

ENGINEERING CONSULTING SERVICES

  • Forensic Engineering
    Forensic Engineering is simply the application of fundamental engineering principles to the investigation of system failures, or of their degradation in performance. The most important skill required is therefore a strong foundation in engineering principles – and the experience of using them. polyX allows you to not only determine what went wrong, but what can be done for the same problem to be avoided in the future.
  • Accident Reconstruction
    Vehicles collide, motorcycles and bicycles crash, pedestrians are struck. The analysis of such accidents employs all three methods of solving Dynamics problems.
