Fracture Mechanics Assessment and Fitness for Service


Fracture Mechanics Assessment and Fitness for Service consulting

"Our analytical tools and experience allow us to resolve a broad range of component deficiencies."

— Eisa Rahmani, Senior Associate

Having investigated and consulted on hundreds of metal structures and pressurized equipment facilities, our professionals are experienced providers of specialty evaluation services—like fracture mechanics assessments—for all types of new and existing metal components. We leverage the combination of recognized industry techniques, nonlinear finite element modeling, laboratory testing, forensic field investigation, metallurgy, field instrumentation, nondestructive testing (NDT) inspection, and years of experience to provide a rapid assessment and actionable solutions for the client.

We help clients develop cost-effective solutions for their challenging new designs, existing infrastructure and facilities, and unexpected failures. We identify risks and safeguards to assist in preventing, controlling, and mitigating the effects of fabrication flaws, in-service deterioration (fatigue, corrosion, environmentally assisted cracking, creep), and unanticipated damage (third-party impact, fire, earthquakes). Our multidisciplinary approach combines knowledge of materials, inspection, fracture mechanics, nonlinear finite element modeling, testing, and years of experience to provide accurate and actionable solutions. We are world renowned for investigating failures and providing clients with accurate assessments. Our engineers provide services for bridges, buildings, cranes, dams, offshore structures, piping, pipelines, pressure vessels, proprietary components, tanks, and transportation structures.
Specific services we offer include developing fabrication flaw acceptance criteria, advising on materials and weld requirements, helping clients develop inspection programs, providing component testing programs for fracture and fatigue challenges, retrofits design, and independent third-party reviews.
