Laboratory Shake Table Testing at ISE

ISE houses a complete dynamic analysis laboratory consisting of an APS Dynamics long stroke shake table, capable of small-scale modal analysis and seismic testing from DC to approximately 200 Hz. Our table is capable of recreating complex waveforms at up to 50 pounds peak force, or a velocity up to 1000 mm/s over 160 mm of linear travel. We have assisted our clients in measuring the response characteristics of specimens for research, aviation, space, military and general civil engineering applications. This table is also used to calibrate every piece of dynamics equipment ISE owns.

Past applications for which clients have found our services useful include:

  • Dynamic response characterization.
  • Fatigue testing.
  • Product and prototype testing.
  • Scientific research and investigations.
  • Forensic investigations.

ISE's physical science laboratory is traceable to standards set forth by the American National Standards Institute (ANSI), the American Society for Testing and Materials (ASTM), the International Organization for Standardization (ISO), and the National Institute of Standards and Technology (NIST). We maintain our own Rubidium atomic time and frequency standard accurate to 10-10 seconds.

Featured Video Clip

ISE performing load testing of concrete test specimens to determine its axial compressive failure characteristics.  

In this example, you can see quite dramatically how concrete fails under a compressive load. Once the ultimate stress is reached, the load carrying capacity of the material rapidly drops off producing the fracturing seen in the video.
