Materials and Testing

We use testing to learn what we need to know to understand failures involving materials.

How can EDT help you? 

Just as a person’s fingerprint can be observed and studied, so can a material be observed and studied to understand its composition and history. An amazing array of features distinguish one material from another, not to mention one metal from another, one type of ceramic from another, one type of plastic from another, and so on.

Other characteristics, including those at the surface and at the microscopic level, provide clues necessary for the analysis of materials characterization and failures involving materials. Testing teaches us what we need to know about a material or a component to understand failures.

Our forensic engineering consultants can support you with the following services.


  • Metallurgy—ferrous and non-ferrous
  • Non-metallic material evaluation—plastics, ceramics, and glass
  • Fracture mode evaluation—overload, fatigue, brittle/ductile
  • Fractography
  • Evaluation of microstructure/Photomicroscopy
  • Optical evaluation/Stereomicroscopy
  • Identification of contaminates/Energy Dispersive Spectroscopy (EDS) and X-ray Defraction Analysis (XRD)
  • Scanning Electron Microscopy (SEM)
  • Chemical analysis (Alloy composition)
  • Mechanical testing
  • Vibration analysis
  • Nondestructive testing
  • Stress analysis
  • Finite element analysis
