Melanie Sarzynski, Senior Associate at Wiss, Janney, Elstner Associates Inc., will present “Engineering Critical Assessments to Evaluate Crack-like Flaws Using Fracture Mechanics” at our February meeting.


Whether a fabrication defect or a result of in-service loading, crack-like flaws can significantly impact remaining life in fatigue sensitive applications subject to cyclic loading. This seminar contains introductory material on engineering critical assessments (ECA) and the use of fracture mechanics to evaluate crack-like flaws in a variety of pressurized equipment and other structures. We will discuss the basics of fatigue assessment and applications where fracture mechanics approaches are more suitable along with the relevant industry guidance documents.

Discussions of inspection techniques, material data requirements, load history treatment, and relevant failure modes are included in the context of a case study, where flaw acceptance criteria were developed for an offshore structure to ensure adequate life.


Melanie leads a wide variety of engineering design and development projects in both upstream and downstream Oil and Gas segments. She has extensive experience in solid mechanics analyses including evaluation of various failure modes to support design and fitness for service (FFS) assessments. Her specialization in advanced finite element analysis, fatigue evaluation, and fracture mechanics assessment has led to frequent consulting on the design and analysis of a variety of components, design and certification of pressure vessels for high pressure applications, and strength and fatigue verification of a variety of equipment.

She is a licensed professional engineer, and holds a bachelor of science, master of science, and doctorate, all in mechanical engineering from Texas A&M University.
