Experience

Venkata Nadakuditi specializes in strength, fatigue, and fracture mechanics in metals with primary interests in steel structures and pressure containing systems. Prior to joining WJE in 2016, Mr. Nadakuditi spent his career in the oil and gas industry. His past work included extreme event strength assessments, extreme event strain-based assessments, defect acceptance criteria, fatigue life predictions, and experimental testing. He has experience using ABAQUS finite element software, special purpose fracture mechanics software programs, and classical methods. He routinely applies methods based on API 579 (Fitness for Service), BS 7910 (flaw assessments), along with other design documents (e.g., API, ASME, AISC, BS, DNV) to calculate defect acceptance criteria, material requirements, remaining fatigue lives, strength, and ductility.

Mr. Nadakuditi’s graduate studies focused on the seismic analysis of horizontally curved steel girder bridges and their parametric response.
