Failure Analysis Services

THE IMPORTANCE OF FAILURE CAUSE ANALYSIS

Polymers, composites, coatings, or ceramics break down and failure analysis identifies the cause. Failure analysis of materials is important for manufacturers that need to make informed design choices for applications and to avoid costly failures.

FAILURE ANALYSIS METHODS FOR NON-METALLIC MATERIALS

A failure analysis team of chemists, engineers, and lab technicians selects the best testing methods to identify failure conditions based on the visible signs of failure and the material.  Failures distinct to different materials require different approaches.

FAILURE ANALYSIS TECHNIQUES

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

Ceramics are often brittle so thermal stress or environmental exposure leads to failure.  Thermal tolerances, fractographic stresses, porosity.

LITIGATION FAILURE ANALYSIS

Litigation and insurance claims need support from competent materials testing experts to reach the appropriate conclusions. Our labs in Ithaca, NY and Louisville, KY provide litigation support to clients in a wide range of industries. Clients rely on IMR to provide the following professional services:

  • Trial Expert Witness Testimony
  • Technical Disposition
  • Legal Consultation
  • Test Witness Services

FAILURE ANALYSIS TESTING PROCESSES

  • Reviewing the steps that occured before the failure
  • Simulating the conditions under which the failure occured
  • Collecting samples for chemical analysis
  • Investigating why some components, if any, remain intact
  • Determining the root cause 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:

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.
