forensic engineering

failure analysis 

is an forensic engineering consulting firm specializing in vibration troubleshooting and failure analysis. Since its founding in 1986 by Chris D Powell, STC's approach has been simple:
  • First, positively identify the basic nature of the problem.
  • Second, gain a thorough understanding of why that problem exists.
  • Finally, design an efficient and effective remedy.

Simple as this may seem, dependable solutions that do not create new problems can be designed only after complete evaluation and proper analysis. STC takes great pride in its reputation for finding economical fixes to industries' most difficult problems.

STC provides: vibration troubleshooting, rotating equipment analysis, stress analysis, failure analysis, noise analysis, modal analysis, strain gage testing, forensic engineering, litigation support and expert witness services.
