Machinery, Equipment and Products
D&A offers expertise in the design and analysis of machines, mechanisms, devices, and mechanical systems. We have investigated accidents and failures involving a wide variety of machinery, equipment, and consumer products. Our capabilities in this area include:
  • Macroscopic and microscopic inspection of failed or suspect components.
  • Non-destructive inspections by magnetic particle, dye penetrant, and x-ray.
  • Fracture surface examination and analysis.
  • Metallurgical analysis including chemical analysis, hardness testing, and optical and scanning electron microscopy (SEM).
  • Experimental and analytical stress analysis including FEA.
  • Fatigue and fracture mechanics analysis.
  • Material, component, and system testing.
  • Maintenance history and upkeep analysis.
  • Codes and standards compliance evaluations.
  • Machine guarding - design and analysis.
  • Tolerance, clearance, and fit analysis.
  • Motion analysis and animation.
  • Design optimization using computer modeling.
  • Statistical analysis of operation, warranty, repair, and accident data to determine probability of failure, failure/accident rates, to quantify risk, and to rank products in relation to peers with regard to performance and/or safety.
