AEMS Inc.
AEMS Inc. was formed based on two decades of research and
development led by Dr. McBride in the area of acoustic
emission monitoring of degradation in materials and the
testing of full-scale structures.
The company's principal successes have involved the use
of acoustic emission monitoring in the aerospace industry.
AEMS is the only company in the world with the demonstrated
capability to detect and locate cracks initiated inside fastener
holes in aircraft structures under dynamic loading without
removal of the fasteners.
AEMS is a service company which uses the acoustic emission method
to locate, identify and monitor defects in materials under stress
in many industries. Acoustic emission is the radiation of high
frequency sound energy as a result of increased damage or defect
growth when a stress is applied to a material. AEMS anufactures,
distributes and leases acoustic emission data acquisition
equipment including sensors, preamplifiers and computerized data
acquisition and monitoring systems. This equipment is designed
primarily for use in the experimental testing of structures and
locating and monitoring internal defects within these structures.
The AEMS equipment can be totally controlled and accessed via
modem. This capability enables AEMS to offer expert monitoring
of laboratory tests or full-scale structures at reasonable
cost by reducing markedly the requirement for the presence of
AEMS staff at the test location.
AEMS has supplied custom built acoustic emission
equipment to the Department of National Defence, Boeing
Commercial Airplane Group, Quality Engineering Test
Establishment and the U.S. Naval Surface Warfare Center.
It is currently carrying out laboratory and full-scale
tests for the Department of National Defence and the
Aeronautical and Maritime Research Laboratory in
Melbourne, Australia. AEMS has successfully completed
projects for Alcan International Limited, Atomic Energy
of Canada Ltd, Quality Engineering Test Establishment,
Les Technologies Industrielles SNC
Inc., Canadian Institute of Guided Ground Transport and
the
Institute of Aerospace Research at the National Research
Council of Canada.

Structural Integrity Monitoring
AEMS has provided consulting services for acoustic emission
monitoring of materials and structures to the aerospace,
atomic energy, civil structures, munitions, and materials process
control industries.
AEMS has demonstrated success in:
* the detection, location, and monitoring of fatigue cracks in
modern fighter and strike aircraft,
* the detection and monitoring of fatigue cracks under rivets in
a multi-site damage configuration,
* the assessment of composite repair patches on full-scale test
articles subjected to static and dynamic loading,
* the determination of the stability of electric primers in
munitions.
AEMS has accumulated an unrivaled data base which relates
acoustic emission to growing fatigue cracks in a variety of
structural steels and aerospace alloys. This data base includes
the effect of heat treatment on the acoustic emission activity
from fatigue crack propagation in metal alloys. The information
in the data base is the basis of the relation between acoustic
emission behavior and fundamental material properties.
AEMS' monitoring of fatigue tests from crack initiation to
failure has refined our ability to detect crack initiation in
components and structures, to track crack growth from initiation
to failure, and to determine the fatigue crack growth loading
conditions.
