THE IMPORTANCE OF FAILURE CAUSE ANALYSIS
Cause of failure can vary based on the material, it's application, and environmental factors. Failure analysis is crucial to understanding why certain components fail under specific conditions, particularly in non-metallic materials. To predict a material's performance and address post-failure, conducting fatigue testing and failure analysis is key.
Our failure analysis services include the evaluation of metals, welds, coatings, finished products, and more. IMR's failure analysis experts have performed thousands of failure investigations, and have experience with a wide range of failure modes, materials and industries.
FAILURE ANALYSIS BY MATERIAL TYPE
Polymers Failure
Polymers typically fail because the wrong material was chosen for an application or there was an interaction with unexpected chemicals. Polymers fail due to chemical exposure, cracking, or aging.
Composites Failure
Often used in applications of high stress, such as aerospace, fiber-reinforced composites fail due to material choice, overestimating the material's load-bearing capacity, or from poor manufacturing practices. Failure is cracks, broken fibers, or delamination.
Coatings Failure
Failures of coatings arise from incompatibility with substrate material or poor adhesion and common causes include delamination, cracking, and erosion.
Metals Failure
Metals typically fail due to material fatigue, corrosion, or excessive stress beyond their design limits. Common failure modes include cracking, fracturing, deformation, or surface degradation caused by environmental exposure and mechanical wear.
Welds Failure
Weld failures often result from poor technique, inadequate materials, or improper preparation. Common causes include cracks, porosity, lack of fusion, or residual stresses, which compromise the weld's structural integrity and durability.
Ceramics Failure
Failed coatings experience erosion, cracking, or delamination if they are unsuitable for a particular application. Failure often occurs due to poor adhesion or an incompatability with the substrate.
FAILURE TESTING METHODS
Once signs of failure have been identified, detailed failure analysis can be performed. These tests include:
Physical Testing of Polymers
Physical Testing of Metals
Mechanical Testing
Chemical Analysis
Microscopy
Fractography
Tests replicate the operational environment of the material in order to simulate failures in real-time, providing insight into the failure cause.

FAILURE ANALYSIS TESTING PROCESSES
- Reviewing the steps that occurred before the failure
- Simulating the conditions under which the failure occurred Collecting samples for chemical analysis
- Investigating why some components, if any, remain intact
- Determining the root causes behind the failure
- Recommending steps to avoid future recurrence
In some circumstances, it aids the failure analysis process to inspect the site where the failures took place. Analyzing failures often involves multi-disciplinary processes. These can include the following:
- Chemical analysis through the use of various spectroscopy techniques
- Environmental exposure testing that approximates the operating conditions at the time of the failure’s occurrence
- Fractography, or the study of fractured material surfaces
- Microscopic examination using scanning electron microscopes and similar equipment
- Mechanical testing utilizing a wide range of analytical equipment, and taking into account component geometry and failure parameters
FAILURE ANALYSIS TESTING SERVICES
IMR Test Labs offers a comprehensive array of failure analysis services for non-metallic materials, including the following:
- Fractography services, which are particularly useful for determining causes of fractures in plastic components and other non-metallic material surfaces
- Investigative chemistry, including adhesive identification, coating contamination, contaminant identification, paint identification, and surface contamination. These are useful for analyzing paint adhesion failures and determining the presence of contaminants in paints and plastics.
- Physical testing for benchmarking plastic part materials and determining distribution of fibers in fiber-reinforced plastics, among others.
- Residual analysis, such as FTIR, scanning electron microscopy and energy dispersive X-ray analysis (there is a close relationship between investigative chemistry and residual analysis) for contaminant identification.
- Thermal analysis for measuring properties such as melting point, crystallization temperature, filler content and mechanical properties as a function of temperature
- Litigation failure analysis, involving trial expert witness testimony, technical disposition, legal consultation, and test witness services
The above services are available for a wide range of materials and parts, including electrical components, fabrics, medical tools and devices, plated parts, plastics, and printed circuit boards.
POLYMER/COMPOSITE FAILURE ANALYSIS SERVICES
Failure analysis of non-metallic materials is necessary to prevent the future recurrence of failures in non-metallic materials. There are different kinds of non-metallic failure analysis techniques. The use of these techniques ultimately depends on the type of non-metallic material to be analyzed and tested.
