IAT has the breadth and depth of resources and capabilities to accommodate projects requiring site investigation, problem analysis, program development, research and development, prototype development and subsequent product manufacturing.

With extensive field/application oriented experience we have the ability to focus quickly and effectively on the root cause of the problems and avoid costly and untimely efforts.

A significant database of practical applications has enabled us to refine the techniques and tools (hardware and software) employed on projects as part of our methodology. Some of the applications include, but are not limited to, Predictive/Failure analysis, Materials Engineering, Specialized NDE techniques, Design to applicable codes and standards, Corrosion, Fatigue and Dynamics analysis, Risk Based Assessment Programs, Structural Analysis and "Equipment Quality and Reliability Programs" (EQRP®).


IAT personnel have been involved in commercial and industrial as well as government research projects ranging in magnitude to hundreds of millions of dollars. The analyses performed have resulted in improved processes and higher reliability to the customer. Whether the problem is a fluid process materials problem or a structural integrity deficiency, IAT has worked efficiently to solve the problem and provide a RESULT or PRODUCT that has added value to the customer now and for years to come. These solutions have been developed for applications in electric utilities, material handling industries, fabrication shops, industrial mills, and transportation systems. Currently under contract with Sandia National Labs, Albuquerque, N.M. (a contractor of the DOE) IAT is providing structural analysis and assessments for all of the hundreds of cranes and hoists located throughout the laboratories located in Albuquerque, NM; Livermore, CA; Tonopah, NV; and Kauai, HA. Our work scope includes the identification of structural deficiencies, the recommendation of corrective action plans to resolve those deficiencies, and the development of programs and processes to implement the plans. A recent example is the identification and replacement of suspect and counterfeit fasteners in the crane systems with product of known quality and origin. Sandia is the first DOE location to have a written program in place for accomplishing this objective.


IAT utilizes four software programs for performing analyses of structures. The first is called STAAD III which stands for 3D modeling capabilities for static and dynamic analysis for steel and concrete structures. The second is COSMOS/M which is a highly recognized and accepted program for finite element analysis of either individual components of a structure or the entire complex structure. It also provides dynamics, vibration, stress analysis, fatigue and bending, heat transfer, and electro-magnetic analysis to name a few, as well as non-linear capabilities. We also utilize ANSYS and ABAQUS FE Modeling programs for their respective attributes relative to fluid structure interactions, seismic response spectra analysis and non-linear elasto-plastic and buckling analyses. Other IAT programs include DAST, Math CAD, Working Model, CELESTIAL SOFTWARE and drafting capabilities utilizing AutoCAD 14 and Graphisoft's 3D ArchiCAD.

Many options exist for software, however, after years of experience using numerous systems, these programs have provided us with the greatest capabilities and results.

IAT has also developed specialized inspection software programs for various industry applications and code requirements.


IAT personnel have years of practical field experience with materials ranging from plastics, composites, ferrous and non-ferrous materials, low alloy high strength steels, to and including exotics such as titanium based alloys.


IAT personnel have been involved in applications oriented research and development for decades. Our personnel have been instrumental in the development of the Acoustic Emission (AE) technology for practical applications and have a wealth of knowledge and experience in interpreting AE data as well as utilizing that data as a portion of the entire analysis process to make materials and component recommendations. We have applied AE successfully to equipment and structures fabricated from wood and composite materials to Cr-Mo Alloys operating around 1000 deg. F. The applications range from annual proof testing to process monitoring during fabrication and continuous monitoring for defect propagation or leakage.

IAT is currently nearing the end of the conceptual development of a new acoustic emission diagnostic instrumentation that will revolutionize the industry. The new concept will employ full digital waveform capture and storage of every event for subsequent post processing analysis. Additionally, the system will provide real time display of the AE activity. No other system has this feature today. Due to the proprietary nature of this system further elaboration cannot be provided at this time.

The most salient features of the IAT methodology is the interpretation and analytical post processing evaluation of the data derived from the AE testing. Of course, these values are preceded in importance only by the correct, planned and purposefully executed application and systematic approach to performing the AE testing initially.

The acoustic emission technology capabilities offered by IAT, which provide for unique qualification, are based upon the diverse experience in applying AE successfully to varied materials and applications. The ESSENTIAL component to these successes is the field derived and laboratory verified experience in interpreting the results of the acoustic emission test data, as it applies to the specific materials and applications or environments.


Our personnel are experts in their respective fields. They have participated in committees and standards writing organizations to develop methods and procedures for use throughout industry. Our structural engineers have specific experience in cranes for commercial as well as heavy industrial applications, such as mill buildings.
